Hypothesis Testing Using Rejection Regions (a) identify the claim and state Ho and Ha, (b) find the critical value(s) and identify the rejection region(s), (c) find the standardized test statistic x², (d) decide whether to reject or fail to reject the null hypothesis, and (e) interpret the decision in the context of the original claim. Assume the population is normally distributed. 24. Gas Mileage An auto manufacturer claims that the variance of the gas mileages in a model of hybrid vehicle is 0.16. A random sample of 30 vehicles has a variance of 0.26. At α = 0.05, is there enough evidence to reject the claim?

Transcribed Image Text:Hypothesis Testing Using Rejection Regions
(a) identify the claim and state
Ho and Ha, (b) find the critical value(s) and identify the rejection region(s), (c) find the
standardized test statistic x², (d) decide whether to reject or fail to reject the null hypothesis, and
(e) interpret the decision in the context of the original claim. Assume the population is normally
distributed.
24. Gas Mileage An auto manufacturer claims that the variance of the gas mileages in a
model of hybrid vehicle is 0.16. A random sample of 30 vehicles has a variance of 0.26.
At α = 0.05, is there enough evidence to reject the claim?
