Question:
Perform the following hypothesis test. Note that you will do both a p-value hypothesis test and a critical-value hypothesis test.
The Motor Trend New Car Buyer’s Guide listed the Ford Taurus as having a highway fuel efficiency of 30 miles per gallon. A consumer interest group conducts automobile mileage tests seeking statistical evidence to identify instances where automobile manufacturers overstate the miles-per-gallon rating for a particular model.
- State the hypotheses that would enable the consumer interest group to conclude that the Ford Taurus fuel efficiency is less than the published 30 miles per gallon.
-
A sample of 50 mileage tests with the Ford Taurus showed a sample mean of 29.6 miles per gallon and a sample standard deviation of 1.8 miles per gallon. What is the
p
-value? What conclusion should be drawn from the sample results? Use \(\alpha =0.01\)
- Repeat the preceding hypothesis test using the critical value approach. Use \(\alpha =0.01\).
