EBook Problems Set - One-Way ANOVA
Problem 1
Jordan was shopping for a ping pong table at Sports Authority, and noticed that there were three tables all similarly priced. He wanted a table that could be taken apart quickly and easily, so he asked the salesman if he knew which one was the best in terms of ease of assembly and disassembly. For some reason, the salesman happened to have a table of the assembly times (sec) for the three tables. Using ANOVA, do you think there is a difference in the average time of assembly for the three brands of ping pong tables?
- Choose one answer.
| Assembly time (sec) | Brand |
| 93.0 | 1 |
| 67.0 | 1 |
| 77.0 | 1 |
| 92.0 | 1 |
| 97.0 | 1 |
| 62.0 | 1 |
| 136.0 | 2 |
| 120.0 | 2 |
| 115.0 | 2 |
| 104.0 | 2 |
| 115.0 | 2 |
| 121.0 | 2 |
| 102.0 | 2 |
| 130.0 | 2 |
| 198.0 | 3 |
| 217.0 | 3 |
| 209.0 | 3 |
| 221.0 | 3 |
| 190.0 | 3 |
- (a) We can say that there is no reason to reject the null that the average assembly times are the same
- (b) We should reject the null that the average assembly times are the same
