1) $7.50 an hour
2) $9 an hour
3) $16.75 an hour
A. 1 only
B. 2 only
C. 3 only
D. 1 and 2 only
E. 2 and 3 only _________________
am still nt getting this... the avg can range max from 20,20,20,20,19 = avg 19.9 & min 5,5,5,5,6 = avg 5.2...I see all 3 as a possibility
The question has given the range from 5 to 20. Hence atleast one's salary should be 5 and other should be 20. With this you would be able to calculate the min and max range of arithmetic mean and choose the answer.
