I need the solution for these problems using SAS (Statistical Analysis System) program.
The solution should include the code, SAS output, and the analysis.
General Instructions: For all problem you should create appropriate graphs to evaluate all assumptions and provide a visual comparison of the treatment effects. Since the computer is doing the computations, it is important that you clearly interpret all result in the context of the problem. Don’t just say the F test is significant. Explain what that means in term of treatments being studied
1) A manufacturer conducted a small pilot study of the effect of the price of one of its products on sales of this product in hardware stores. Sixteen stores used in the study with four in each of the four geographic regions and one of each size in each region. Four price level were used in the study and were assigned to the stores so that each price level was assigned to each combination of region and store size. Identify the type of design used and analyze the data in file T1P2.csv to see if there is an impact on sales and if there is, identify the nature of the impact
2) A physiologist studied the effects of three reagents on muscle tissue in dogs. Ten litters of three dos each were randomly selected and the three reagents were randomly assigned to the three dogs in each litter. The data from the to see if there is a difference between reagents. If there is a difference, conduct an appropriate multiple comparisons procedure to identify the differencesexperiment are in file T1P3.csv. Identify the type of model and analyze the data
3) A rehabbilitation center was interestedin the impact of fitness level at the start of therapy to the time in physical therapy required to complete rehabilitation. Data were collected for 24 patients who had undergone a similar corrective knee surgery and the individual was racked on their fitness level as 1-below average, 2-average, 3-above average. The number of days required for physical therapy for each individual is in TpP4.csv. Prepare a comparative graphical analysis of the data and conduct an ANOVA to test if there is a difference in mean recovery time.
4) An engineer is studying the mileage performance characteristics of five type of gasoline additives. In the road test cars are to be used as blocks, there is only enough time to run four of the five additives in each car. The mileage data for this experiment are in file T1P5.csv. What type of design in this?
Conduct an analysis to identify whether some additives are better than others.
