1. 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 two weeks before and after the workshop. Here are the maximum speeds for each person during the two weeks before, and the two weeks after, the workshop. Using the .05 significance level, should we conclude that people are likely to drive more slowly after such a workshop? Use the steps of hypothesis testing to answer this question.
