We are experiencing longer than “usual” wait times. I got this message on 75% (i.e., 24) of 32 calls for customer service. For simplicity assume the maximum wait time is 11 minutes and use 11 bins in your histograms.

a) Suppose “usual” means the mode of the wait time distribution. If possible draw a histogram where 75% of the wait times are above the mode.

b) Suppose “usual” means the median of the wait time distribution. If possible draw a histogram where 75% of the wait times are above the median.

c) Suppose “usual” means the mean of the wait time distribution. If possible draw a histogram where 75% of the wait times are above the mean.
