A study is done to test the claim that Company A
retains its workers longer than Company B. Company A samples 16
workers, and their average time with the company is 5.2 years with
a standard deviation of 1.1. Company B samples 21 workers, and
their average time with the company is 4.6 years with a standard
deviation of 0.9. The populations are normally
distributed.
write the hypothesis in symbolic form.
determine the value of the test statistic.

determine if you should reject the null hypothesis or fail to
reject the null hypothesis.
write a conclusion addressing the original claim.
All work must be shown in order to receive any
credit.
