Textbook Question
Chapter 15, Problem 15.98ACI
Does fatigue lead to more defectives? A manufacturer wants to determine whether the number of defectives defect produced by its employees tends to increase as the day progresses. Unknown to the employees, a complete inspection is made of every item that was produced on one day, and the hourly fraction defective is recorded. The resulting data are given in the next table. Do they provide evidence that the fraction defective increases as the day progresses? Test at the α = .05 level.
| Hour | Fraction Defective |
| 1 | .02 |
| 2 | .05 |
| 3 | .03 |
| 4 | .08 |
| 5 | .06 |
| 6 | .09 |
| 7 | .11 |

Test d'égalité des espérances: observations pairées
A television news channel samples 25 gas stations from its local area and uses the results to estimate the average gas price for the state. What’s wrong with its margin of error?
You’re fed up with keeping Fido locked inside, so you conduct a mail survey to find out people’s opinions on the new dog barking ordinance in a certain city. Of the 10,000 people who receive surveys, 1,000 respond, and only 80 are in favor of it. You calculate the margin of error to be 1.2 percent. Explain why this reported margin of error is misleading.

The head of civil engineering and municipal services decided to structure an experimental plan to detect if there could be significant differences in project evaluation. Seven projects were selected, each of which had to be evaluated by each of the two estimators, with the order of the projects submitted being random. The obtained estimates are presented in the table below. a) Complete the table above by calculating: i. The differences (A-B) ii. The sum of the differences iii. The mean of the differences iv.
