Exercise 5 (15) In the process of learning how toconduct a sign test, each student inevitably punches their computerscreen several times. I have found that students who punch theirscreens during this exercise can be separated into two categories.The first category believes that this statistics course would bebetter if they did all of their statistics by hand. The secondcategory is pleased that the course is taught using R. Below is thenumber of times a computer screen is punched by a student in eachcategory. Assume all assumptions have been met.
Hates R | Loves R |
3 | 7 |
6 | 10 |
7 | 11 |
4 | 8 |
5 | 9 |
- By hand, test the hypothesis that there is nodifference between the two categories in relation to how many timesthey punch their computer screen. Provide the scrap paper used toconduct this test.
- By hand, calculate the 95% CI of thedifference between the means.
