Given the data set:

(a) Write a SAS program to compare the sales records of the company's three salespeople. (Compute the sum and mean For the number of visits, phone calls, and units sold for each salesman.) Note that the values for "Units sold" contain commas. Since you don't know how to read data values with commas (you use a COMMA in format), omit the commas when you enter your data values.

(b) Plot the number of visits against the number of phone calls. Use the value of Salesperson (the first character in the name) as the plotting symbol (instead of the usual A, B, C, etc.).

(c) Make a frequency bar chart for each salesperson for the sum of *units sold."
