4. At Bradbury Hardware Store, there are 6 cash register stations in the front of the store. When a customer is ready to check out, he or she must choose the line that will probably be shortest (no easy task). Over a period of time, the store manager has looked at the time stamps on register tapes to establish a mean waiting time for each cashier in his or her line through at least 150 customers. Here is what he found: a. Stephen Mean 6.55min. Std. Dev.-2 Shape Normal b. Margie Mean 8.05min. Std. Dev.-3 Shape Bimodal c, Glenn Mean = 5.45min. Std. Dev. = 4 Shape = Skewed Left d. Lydia Mean 7.05min. Std. Dev.-4.5 Shape Skewed Right e. Nick f. Eleanor Mean=9.15min. Std. Dev. 1.5 Shape = Normal Mean 5.10min. Std. Dev. 5 Shape Uniform Explain in detail which register you would be likely to go to first, second, third, etc.
