To testthis claim within his own company, a health insurance companyexecutive takes a random sample of eight employees and records thetotal number of claims processed by each employee over four Mondaysand four Tuesdays. The following gives the recorded data:

Employee12345678
Mondays3847484546414243
Tuesdays4246485449473949

Using the five-step format, test whether the claim that morework is accomplished on Tuesdays is correct for this company. Makesure to clearly state the null and alternative hypotheses, definethe test statistic and null distribution, calculate the teststatistic, find bounds the p-value, and make a conclusion in termsof the problem. (Hint: This data is paired.)

\"5 Step Format\"

1. State H0 and Ha.

2. State α.

3. State the form of the 1 − α confidence interval you will use,along with all the assumptions necessary.

4. Calculate the 1 − α confidence interval.
