Chapter 10.3, Problem 27E
A manufacturer produces both a deluxe and a standard model of an automatic sander designed for home use. Selling prices obtained from a sample of retail outlets follow.
| Retail Outlet | Model | Price ($) |
| Deluxe | Standard | |
| 1 | 39 | 27 |
| 2 | 39 | 28 |
| 3 | 45 | 35 |
| 4 | 38 | 30 |
| 5 | 40 | 30 |
| 6 | 39 | 34 |
| 7 | 35 | 29 |
- a. The manufacturer’s suggested retail prices for the two models show a $10 price differential. Use a .05 level of significance and test that the
mean difference between the prices of the two models is $10. - b. What is the 95% confidence interval for the difference between the mean prices of the two models?
