Question
In order to determine whether the median distance for the X-Special golf ball exceeds the median distance for the best-selling golf ball, six golfers were selected and asked to hit each ball with their driver. The distance was recorded. The following data were observed.
| Golfer | X-Special | Best Seller |
| 1 | 240 | 233 |
| 2 | 267 | 270 |
| 3 | 255 | 240 |
| 4 | 234 | 230 |
| 5 | 250 | 260 |
| 6 | 285 | 270 |
Based on these data, and testing at an alpha = 0.025 level, the critical value for the Wilcoxon Matched Pairs Signed Rank test is 2.
