Customers were surveyed after leaving a restaurant of which was known to be of poor quality service. Of 5594 male customers surveyed, 3547 reported some poor service; of 3469 female customers surveyed, 1447 reported some poor service.

Perform a hypothesis test to determine if there is a difference in the proportions of male and female customers who experienced poor service. Let p_mand p_fbe the proportion of all male and female customers, respectively, who received poor service. Calculate sample proportions to 3 decimal places; calculate the standard error to 5 decimal places.

Question 1. Calculate the value of the test statistic for this hypothesis test:

Question 2. If the significance level= .05 is used, what is the rejection region for this hypothesis test? Find the upper and lower bound.
