Archie is fed up with waiting in line at his local post office and decides to take action. Over the course of the next few months, Archie records the waiting times for each of a random selection of 23 post office visits made by him and other customers. These waiting times (in minutes) are summarized in the following histogram. Frequency 6- 2- 0 6 S 12 18 Waiting time (in minutes) 24 30 Based on the histogram, estimate the mean waiting time (in minutes) for Archie's sample. Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place. E mn C 2.9 B K
