Question
Regional Manager Sue Collins would like to know if the mean number of telephone calls made per 8-hour shift is the same for the telemarketers at her three call centers (Austin, Las Vegas, and Albuquerque). A simple random sample of 6 telemarketers from each of the three call centers was taken and the number of telephone calls made in eight hours by each observed employee is shown below.Observation | Center 1 Austin | Center 2 Las Vegas | Center 3 Albuquerque |
| 1 | 82 | 72 | 71 |
| 2 | 68 | 63 | 81 |
| 3 | 77 | 74 | 73 |
| 4 | 80 | 60 | 68 |
| 5 | 69 | 70 | 76 |
| 6 | 78 | 73 | 80 |
| Sample Mean | 75.667 | 68.667 | 74.833 |
| Sample Variance | 33.867 | 33.467 | 26.167 |
Using
= .10, test for any significant difference in the mean number of telephone calls made at the three call centers. Answer
