Chapter 21.III, Problem 2RE
You are the sales manager of the Esquire Sportswear Company. Last week your 30 salespeople reported the following automobile mileage while making sales calls to retail stores around the state:
| 385 | 231 | 328 | 154 | 283 | 86 | 415 | 389 | 575 | 117 | 75 | 173 | 247 | 316 | 357 |
| 211 | 432 | 271 | 93 | 515 | 376 | 328 | 183 | 359 | 136 | 88 | 438 | 282 | 375 | 637 |
a. Group the data into seven classes of equal size (0-99, 100-199. 200-299. 300-399. etc.) and construct a frequency distribution of the mileage.
b. Calculate the mean of the grouped data by using 49.5, 149.5, 249.5. etc., as the midpoints.
c. Using the grid provided below, prepare a histogram of these data to illustrate your salespeoples’ mileage graphically.
