2. (b)

Total number of graduates sample = 200

Number of graduate sample had starting salaries of less than $25,000 = 100

percentage of graduate sample had starting salaries of less than $25,000 = (100/200)*100 = 50 %

2.(c)

Total number of graduates sample = 200

Number of graduate sample had starting salaries at least $20,000 = 160
