Answer to Question #49818 in Statistics and Probability for Brian

Question

2. 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.
