A sample of five people who were convicted of speeding were ordered by the court to attend a workshop. A special device put into their cars kept records of their speeds for two weeks before and after the workshop. The maximum speeds for each person during the two weeks before and the two weeks after the workshop follow. Before | [ After Stacey 64 Quetta 68 ~pavar | Hampton | Using a 5% significance level, can we conclude that people are likely to drive significantly faster on average after such a workshop? Assume that speeds of drivers, measured in miles per hour, is normally distributed. 1.
