# Question

When the 636 male workers in the 2008 GSS were asked how many hours they worked in the previous week, the mean was 45.5 with a standard deviation of 15.16. Does this suggest that the population mean work week for men exceeds 40 hours? Answer by:

a. Identifying the relevant variable and parameter.

b. Stating null and alternative hypotheses.

c. Reporting and interpreting the P-value for the test statistic value of t = 9.15.

d. Explaining how to make a decision for the significance level of 0.01.
