Assignment: Testing a Manufacturer’s MPG Claim: Part 2
Note: Last week, you submitted Part 1 of this Assignment. This week, you will complete and submit only Part 2 (including the Conclusion).
Companies often develop and test hypotheses about their products. For example, car manufacturers will test their cars to determine fuel efficiency and miles per gallon. To ensure that products are safe and that they perform as advertised, regulatory and consumer protection groups also test companies’ claims.
For this Assignment, you are working at a firm that conducts independent testing for heavy industry. Recently, an automobile manufacturer has been in the news for complaints about the highway gas mileage of their latest model minivan. You receive a contract from a consumer action group to test and write a report on the company’s claim that its minivans get 28 miles per gallon on the highway. The car company agrees to allow you to select randomly 35 low-mileage fleet minivans to test their highway mileage. Your test results gave you the following data:
29.7 24.5 27.1 29.8 29.2 27.0 27.8 24.1 29.3
25.9 26.2 24.5 32.8 26.8 27.8 24.0 23.6 29.2
