In anticipation of Mary’s request for comparative analysis, it will be useful at this time to do some research. You know that you can obtain the financials of companies within the same sector or Standard Industry Code as Apix Printing (e.g., commercial printing), and that the North American Industry Classification System (NAICS) Standard Industry 2012 code for Apix Printing is presently 323111. Use Hoover’s Pro to search for two other companies in the same industry as Apix Printing. 

When you get to work the next day, you see the following e-mail from Mary:

Here is the list of financial ratios you asked for. I need you to explain the computation of each and compute these for Apix’s results for the financial statements you are using for the PowerPoint presentation. Also, compare Apix’s 2-year trend results to that of two other firms in the sector. Indicate how each of Apix’s ratios differ, and indicate whether the two other companies’ ratios or Apix’s ratios are indicative of better performance. 

Explain the computation for each of the following, and compute each for Apix and two other companies in the same industry as Apix Printing:

• Current ratio 
• (Long-term) debt to equity ratio 
• Gross margin percentage 
• Net profit margin percentage 
• Return on equity percentage 

Present your findings of the above data in a table. Add a paragraph that summarizes your results, indicating whether investors would find the financial analysis results of Apix competitive as compared to rivals in the sector. Be sure to include both positive and negative trends in your analysis.

For your project this week you will need to do the following:

Description 

 

You have been contacted by the ABC School District to design a modular unit that can be divided in two 

or more classrooms as needed. A plan view of the modular units is shown below. Each unit will have an 

overhang on both sides of the longest building dimension. Columns can only be located along the main 

perimeter. All main structural members (slab, beams, joists, columns and footings) must be of reinforced 

concrete (f’c = 4000 psi). ACI 318-11 building code requirements must be satisfied. Assume that the units 

are going to be build in San Antonio, Texas. The architect requires that between top of floor and bottom of 

ceiling the clear distance should be 12 feet. The floor slab is going to be 6-inch thick. The bearing 

capacity of the soil has been estimated to be 4500 psf. The water table is very deep. Only Gr.60 steel is 

available. The roof of the modular unit is going to have solar panels covering 100% of the area (including 

overhangs). Reinforced masonry walls will be used in the longitudinal direction. 

 

This portion of the Final Exam draws upon the knowledge and skills you acquired throughout this course by asking you to perform an SPSS analysis. Read the three case studies below and choose the appropriate statistical procedure. Using the Final Exam Data Set, run the appropriate correlation or regressions procedure, analyze the data, and report the results in a properly formatted APA Results section.

Please be sure to include the following elements in your Results:
1. The assumption tests and their results (include graphs if you used them)
2. An adequate report of the descriptive statistics
3. The null hypothesis
4. The rationale for the chosen statistical procedure and results of the statistical procedure, including effect size and power
5. The decision regarding the null hypothesis

For the purpose of the Final Exam, do not transform or change any variables if assumptions are not met. Conduct and report the most appropriate parametric procedure; simply note violations and identify the nonparametric alternative that could be conducted.

You may consider the following parametric statistical procedures to respond to the questions:
• One-sample t Test
• Dependent t Test
• Independent t Test
• One-Way ANOVA
• Two-Way ANOVA
• Repeated Measures ANOVA
• Bivariate Correlation (Pearson r and Spearman rho)
• Partial Correlation
• Bivariate Linear Regression

NOTE: While you were allowed to work with your peers for the other SPSS Assignments, you must work individually for this Final Exam.

Case Study 1

An educational statistics professor is examining his grade book to determine the relationship and differences among a variety of assignment scores. He is examining these scores to determine if his course is effective. Every semester, the professor gives his students a pretest and a posttest to determine if they improved in their understanding of the course concepts. Thus, the first question he examines is as follows : Is there a difference in the number of points students earned on their educational statistics pretests and posttests?

 

 

Promotion of Supermarket Vegetables
A supermarket chain is interested in exploring the relationship between the sales of its store-brand canned vegetables (Y variable), the amount spent on promotion of the vegetables in local newspapers (X1 variable), and the amount of shelf space allocated to the brand (X2 variable). One of the chain’s supermarkets was randomly selected, and over a 20-week period X1 and X2 were varied. Develop the multiple regression model for predicting the sales that explains how advertising expenditures and shelf space influence sales. ( data info attached )

Study the problem “Promotion of Supermarket Vegetables” and download the data from PromotionsData.xlsx. (Available on BB9)
Form the following analysis of the data:
1) Construct the correlation matrix for the variables Sales, AdExp, and ShelfSpc

 

2) Run a multiple regression model with Sales as the dependent variable and AdExp and ShelfSpc as the independent variables (Model 1).
3) Run a multiple regression with Sales as the dependent variable and AdExp, SmallShelf, LargeShelf, SmallAdExp, and LargeAdExp as the independent variables (Model 2).

 

4) Remove insignificant variables from the model estimated in the previous step (Model 2) and re-run a multiple regression model (Model 3).

2. In a population of heights of 10,000 women, m = 63 inches and s = 5 inches. The number of

 

heights in the population that fall between 66 inches and 68 inches is 1156.

 

 

3. In a normal distribution, approximately 91.31% of the area under the curve is found to the

 

right of a point -1.36 standard deviations from the mean.

 

 

4. Approximately 92.5% of the area under the normal curve is located between the mean and

 

+/-1.78 standard deviations from the mean.

 

 

5. It is incorrect to say that the standard error of the mean is also the standard deviation of a

 

sampling distribution of means.

 

 

6. The most practical way to reduce standard error is to increase the sample size.

 

 

7. The standard error of a sampling distribution of means can be larger than the standard

 

deviation of the population upon which the sampling distribution is based.

 

 

8. With  remaining constant, increasing the sample size yields a smaller standard error.

 

 

 

9. As n increases, the width of a confidence interval for m increases, assuming s is constant.

 

 

10. Expanding confidence from 95% to 99% will increase the width of a confidence interval.

 

 

11. Given n = 100 and s^2 = 400, the estimate of the standard error of the mean is 2.

 

 

12. Given a sample with n = 100, Ho: m = 500, H_a: m ¹ 500, and  = 0.05, the null hypothesis

 

can be rejected if and only if z ³ 1.645 or z £ -1.645.

 

 

13. In problem 12 if x-bar = 505 and s = 20, the null hypothesis can be rejected with p = 0.0062.

 

 

14. Convicting an innocent defendant is a Type I Error.

 

 

1. If n = 16, x-bar = 43 and s = 4, then a 98% confidence interval for  is (40.869, 45.131).

 

 

16. The table value of Z required to reject a null hypothesis at a given -level is larger for a

 

two-tailed test than for a one-tailed test.

 

 

17. According to the Central Limit Theorem, a distribution of sample means based on a sample of

 

n = 7 will approximate normality even if the data in the parent population are not normal.

 

 

18. When performing hypothesis tests or computing confidence intervals based on large samples,

 

it is necessary to assume that the data in the parent population(s) are distributed normally.

 

 

19. To estimate  within two units with 95% confidence and  = 10 requires n be at least 100.

 

 

20. If a two-tailed test assumes a 5% rejection region, then the total rejection region is 5%.

 

 

21. The p-value for a hypothesis test resulting in z < -2.74 is approximately 0.0310.

 

 

22. Allowing a guilty defendant to go free is a Type II Error.

 

 

23. The Student t-distribution approaches a normal distribution as the df get larger.

 

 

24. Statistical significance is the rejection of a null hypothesis at some alpha level.

 

 

25. Two samples of size 25 each yielding x-bar = 6.47, Sx = 1.14, y-bar = 6.17, and Sy =1.166

 

show a significant difference between means with a p-value of 0.3623.

 

Through this real-world project you will design a secure, scalable, and responsive database security plan and requirements definition document for a system of your choice. Your chief security officer has given you the assignment of defining, developing, and documenting a database security policy and plan for your databases. This document shall define who is responsible for security in your organization and what authority is granted to that person in the advent of a security breach. Additionally, policies and procedures should be defined and documented that outline the daily administrative tasks, definition of security rules and methods, and the enforcement of those rules. Your job is not to implement the requirements but to define what the requirements are and to document them. While working on your project, assume the roles of the chief security officer, database designer, database administrator, and chief applications designer.

Each week you should add analysis and design elements to your project by following and extending the topics discussed in class. Plan to develop your project using a single Microsoft Word document. The format will be discussed in class. In addition, you should be prepared to share your project’s status and issues each week in class.

The final version of your project must be posted to the Dropbox. Here is a step-by-step outline to aid you in completing your project. Feel free to propose modifications that may better suit your specific goals.

It is important that you are able to apply demand and supply analysis to events that you experience or read about in your life. Find an article from a newspaper or periodical that illustrates a market. Complete the following steps:

• Underline one sentence (market) to be analyzed (the article may discuss several markets).
• Identify the good or service.
• Discuss the relevant prices and quantities for the current market situation and identify what you believe is the equilibrium price and quantity.
• Discuss any shifts that have taken place in the supply or demand curves. Make certain that movements along a curve are not confused with shifts in the curves themselves.

Complete a one page analysis of your article. The answer should be concise and the market you are analyzing should be clearly stated at the top of the page. Be sure to include a proper APA citation for your article.

 

You can make this your own, makes it easier, please be conservative. Allow me to know what you have selected prior to the research.
