Question

You are manager of a specialty coffee shop and collect data throughout a full day regarding waiting time for customers from the time they enter the shop until the time they pick up their order )What type of distribution do you think would be most desirable for the waiting times: skewed right, skewed left, mound-shaped symmetric? Explain O A skewed left distribution would be the most desirable because this would mean there are never any long waiting times. 0 A skewed right distribution would be the most desirable because this would mean there are never any long waiting times. O A skewed left distribution would be the most desirable because this would mean there are a lot of short waiting times and only a few long waiting times O A mound shaped symmetric distribution would be the most desirable distribution because this would mean are a lot of short waiting times and only a few long waiting times. A skewed right distribution would be the most desirable because this would mean there are a lot of short waiting times and only a few long waiting times (b) What if the distribution for waiting times were bimodal? What might be some explanations? 0 A bimodal distribution for waiting times might exist if almost all orders are filled very quickly and only a couple orders get lost throughout the day O A bimodal distribution for waiting times might exist if almost all orders take a long time to fill and only a couple orders are filled very quickly. O A bimodal distribution for waiting times might exist if orders are filled at different rates during busy and slow periods. O A bimodal distribution for waiting times might exist if almost all orders are filled in approximately the same amount of time.

Explanation / Answer

The correct answer is:

First option which says that almost all orders are filled very quickly and only a couple orders get lost throughout the day (these two result in the two modes or peak waiting times).

(Note: If it is possible to select more than one answer, also select the third option, which in one scenario can be true)

Third option which is binomial distribution for waiting times may exist if orders are filled at different rates during busy and slow periods
