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.
