The time married men with children spend on child care averages 6.4

a. What are the hypotheses if your group would like to determine if the population mean number of hours married men are spending in child care differs from the mean reported byTime in your area?

b. What is the sample mean and the p-value?

c. Select your own level of significance. What is your conclusion?

Part 1: Assume that we know sigma (the population stdev of ALL married men in your area — their time spent on child care per week) is 2.5 hrs. Answer 30 (a) using BFDA and conducting a “Normal Test for Mean” with a significance level = 0.05.
Part 2: Now answer 30 (a) assuming we DO NOT know sigma, the population stdev. Conduct a “t-Test for Mean.”  For Step 4, use =TINV for the reject rule. For Step 5, use =TDIST for the p-value. Produce a new Results Table and Business Answer.
