The number of hours taken by transmission mechanics to remove, repair and replace transmissions in one of the Transmission Fix. It stores one day last week is recorded as follows:
| 4.3 | 2.7 | 3.8 | 2.2 | 3.4 |
| 3.1 | 4.5 | 2.6 | 5.5 | 3.2 |
| 6.6 | 2.0 | 4.4 | 2.1 | 3.3 |
| 6.3 | 6.7 | 5.9 | 4.1 | 3.7 |
Construct a frequency distribution with intervals of 1.0 hour from these data. What conclusions can you reach about the productivity of mechanics from this distribution? If Transmission Fix-It management believes that more than 6.0 hours is evidence of unsatisfactory performance, does it have a major or minor problem with performance in this particular store?
