In a Study of Distances Traveled by Buses Before the First

question 150

Short Answer

In a study of distances traveled by buses before the first major engine failure, a sample of 191 buses results in a mean of 96,700 miles and a population standard deviation of 37,500 miles. Calculate the p-value corresponding to the test statistic used to test the claim that the mean distance traveled before a major engine failure is more than 90,000 miles and, applying the p-value rule, determine if the null hypothesis can be rejected at α = .01.
