The time married men with children spend on child care averages 6.0 hours per week. You belong to a professional group on family practices that would like to do its own study to determine if the time married men in your area spend on child care per week differs from the reported mean of 6.0 hours per week. A sample of 40 married couples will be used with the data collected showing the hours per week the husband spends on child care. The sample data are contained in the table below.

10.9 5.2 11.1 4.9
4.0 9.9 10.1 6.6
4.0 10.0 5.0 4.6
3.0 9.5 9.3 3.7
6.7 2.3 1.7 8.9
9.2 7.1 10.2 0.8

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 in your area?

b. What is the sample mean (to 1 decimal)?

Calculate the value of the test statistic (to 2 decimals).

What is the p-value?

- Select your answer -lower than .01between .01 and .025between .025 and .05between .05 and .10between .10 and .20greater than .20Item 5

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

Considerthepossibilitythatgovernmentspendingincreasestheamount of hours to be worked in a given time period, say by providing child care. Assume again that the initial amount of consumption and leisure are still affordable after an increase in spending. How will an increase in government spending affect consumption, hours worked, output and welfare? [Hint: think about how we constructed the bounds on our labor leisure model in terms of hours worked] Suppose instead of do- mestic government spending we consider remittances sent from abroad (think...
