Five soft drink bottling companies have agreed to implement a time management program in hopes of increasing productivity (measured in cases of soft drinks bottled per hour). The number of cases of soft drinks bottled per hour before and after the implementation of the program are listed below. Company 1 2 3 4 5 Before 500 475 525 490 530 After 510 480 525 495 533 Test, at level 0.05, whether the time management has been effective in increasing productivity. Let Tobs be the observed value of the appropriate test statistics. Group of answer choices Since Tobs = -2.82 > -4.604 we do not have enough evidence to conclude that the time management program has been effective in increasing production. Since Tobs = -2.82 < -2.132 we can conclude that the time management program has been effective in increasing production. Since Tobs = -1.64 > -2.132, we do not have enough evidence to conclude that the time management program has been effective in increasing production. Since Tobs = -1.64 < -1.533,we do have enough evidence to conclude that the time management program has been effective in increasing production.

Question
Five soft drink bottling companies have agreed to implement a time management program in hopes of increasing productivity (measured in cases of soft drinks bottled per hour). The number of cases of soft drinks bottled per hour before and after the implementation of the program are listed below.
| Company | 1 | 2 | 3 | 4 | 5 |
| Before | 500 | 475 | 525 | 490 | 530 |
| After | 510 | 480 | 525 | 495 | 533 |
Test, at level 0.05, whether the time management has been effective in increasing productivity.
Let Tobs be the observed value of the appropriate test statistics.
