The waiting time to get food at a fast-food restaurant is 4.6 minutes on average with standard deviation of 2.2 munutes. Suppose that a sample of 33 customers is randomly selected. A. What are the mean and standard deviation of the sample mean waiting time of 33 customers? Mean = Standard Deviation (standard error of the mean) = minutes Round standard error to 5 decimal places. B. What is the probability that the average waiting time of 33 customers is less than 4.3 minutes? Round to 4 decimal places. C. What is the probability that the average waiting time of 33 customers is greater than 4.8 minutes? Round to 4 decimal places. D. What is the probability that the average waiting time of 33 customers is between 4.3 and 4.8 minutes? Round to 4 decimal places. Answer: minutes Answer: Answer:
