Five people who were convicted of speeding were ordered by the court to attend a workshop. A special device placed in their cars kept a record of their speeds for 2 weeks before and after the workshop. The maximum speeds for each person during the 2 weeks before and the 2 weeks after the workshop follow:
Participant | Before | After |
L. B. | 65 | 58 |
J. K. | 62 | 65 |
R. C. | 60 | 56 |
R. T. | 70 | 66 |
J. M. | 68 | 60 |
Using the .05 significance level, should we conclude that people are likely to drive more slowly after this workshop? Use hypothesis testing.
