A certain popular model of motorcycle advertises that it gets 30 miles per gallon in city driving. A consumer group wants to see if this is true or if gas mileage is something other than 30 miles per gallon. They purchase a sample of 4 cars of this model and find the gas mileage of each after 15,000 miles of city driving. They compute the mean gas mileage x-bar is 29.5 miles per gallon. Assume normality with a mean u and a standard deviation = 2 miles. Here are the hypotheses being tested: Ho: u = 30 Ha: u /= 30 What is the p-value of the test statistic? A. 0.05 B. 0.10 C. 0.3085 D. 0.4785 E. 0.6170 i think its C, what do you think?
