Archie is fed up with waiting in line at his local post office, and plans to contact his congresswoman. Archie without data to back It up. So to improve his case, over the next few months Archie records the waiting time for a selection of 23 post office visits made by h and other customers. These walting times (in minutes) are summanzed in the following frequency distribution. Walting time (in minutes) Frequency O to 6 7 to 13 9. 14 to 20 21 to 27 6. 28 to 34 Based on the frequency distribution, using the midpoint of each data class, estimate the mean waiting time for the data Archie collected. For your intermedia computations, use four or more decimal places, and round your answer to one decimal place.

Question
Archie is fed up with waiting in line at his local post office, and plans to contact his congresswoman Archie knows that his complaint will not be well received without data to back It up. So to improve his case, over the next few months Archie records the waiting time for a selection of 23 post office visits made by him and other customers. These walting times (in minutes) are summarized in the following frequency distribution. Walting time (in minutes) Frequency O to 6 2. 7 to 13 6. 14 to 20 21 to 27 9. 28 to 34 Based on the frequency distribution, using the midpoint of each data class, estimate the mean waiting time for the data Archie collected. For your intermediate computations, use four or more decimal places, and round your answer to one decimal place.
