The Adecco Workplace Insights Survey sampled men and women workers and asked if they expected to get a raise or promotion this year (USA today, February 16, 2012). Suppose the survey sampled 200 men and 200 women. If 104 of the men replied Yes and 74 of the women replied Yes, are the results statistically significant so that you can conclude a greater proportion of men expect to get a raise or a promotion this year?
a. State the hypothesis test in terms of the population proportion of men and the population proportion of women.
b. What is the sample proportion for men? For women?
c. Use a .01 level of significance. What is the p-value and what is your conclusion?
