Per the Barron's report the average weeks unemployed is 21.5 (population mean) with a population standard deviation of 5 weeks and a sample of 55. What is the expected value of the mean to one decimal?
Homework Answers
Solution :
Given that ,
mean = 
= 21.5
standard deviation = 
= 5
n = 55
expected value of the mean
E(X) =
E(X) = 21.5
