< rev The board of a major credit card company requires that the mean wait time for customers when they call customer service is at most 5.00 minutes. To make sure that the mean wait time is not exceeding the requirement, an assistant manager tracks the wait times of 32 randomly selected calls. The mean wait time was calculated to be 5.53 minutes. Assuming the population standard deviation is 1.86 minutes, is there sufficient evidence to say that the mean wait time for customers is longer than 5.00 minutes with a 98 % level of confidence? Step 3 of 3: Draw a conclusion and interpret the decision. Answer 4 Points Tables Keypad Keyboard Shortcuts We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 98 % level of confidence to support the claim that the mean wait time is longer than 5.00 minutes.
