A company that produces top-of-the-line batteries claims that its batteries are good, on average, for more than 65 months. A consumer protection agency tested 25 such
batteries to check this claim. It found that the mean life of these 25 batteries is 63.4 months, and the standard deviation is 3 months. If we test the company's claim at a 5%
significance level, what is the decision? Assume normality.
Fail to reject Ho because the test statistic is in the critical region and the p-value is greater than the significance level.
Reject Ho because the test statistic is not in the rejection region and the p-value is greater than the significance level.
Reject Ho because the test statistic is in the critical region and the p-value is greater than the significance level.
Reject Ho because the test statistic is in the rejection region and the p-value is less than the significance level.
Fail to reject Ho because the test statistic is not in the critical region and the p-value is greater than the significance level.
