The Sashelp.Thick data set simulates measurements of coal seam thickness (in feet) taken over an

approximately square area. The variable Thick contains the thickness values. The coordinates are

offsets from a point in the southwest corner of the measurement area, where the unit for the north and

east distances is 1,000 feet.

(a) The data set MoreCoal.txt is a space delimited data set containing 25 more simulated coal seam

thickness measurements. Load this data set into SAS. Create a new SAS data set called ‘Coal’

by stacking the Sashelp.Thick data set onto the data set you create using MoreCoal.txt.

(b) In the Coal data set, create a new variable called ‘OriginDistance’ that is the distance (in 1,000

feet) of the coal seam thickness’s measurement location from the southwest corner of the measurement

area (i.e., where East = 0 and North = 0). To do this, use the formula for calculating

distance in a plane. Let the east variable represent the x-axis and the north variable represent

the y-axis.

(c) Sort the Coal data set by the OriginDistance variable in ascending order. Print the sorted Coal

data set and report the output.

(d) Use subsetting to create a data set consisting only of observations with coal seam thickness greater

than 42. Print the resulting data set and report the output.

I have attached the .txt file. let me know if you have any question.
