Economists theorize that the recent recession has affected men more than women because men are typically employed in industries that have been hit hardest by the recession, such as manufacturing and construction. Women, on the other hand, are typically employed in services such as health care and education, which are considered more recession resistant. A sample of 175 men and a sample of 140 women were drawn. Eighteen in the group of men were unemployed; 12 in the group of women were unemployed.

a. Perform a hypothesis test using a = 0.05 to determine if the unemployment rate for men is higher than the rate for women.

b. Determine the p-value and interpret the results.

c. Verify your results using PHStat.
