A sample of 39 cars of a certain kind had an average mileage of 34.0 mpg with a standard deviation of 4.7 mpg. Assuming that mileage is approximately normally distributed, test the hypothesis that the average mileage for all cars of this type is no less than 32.9 mpg at the 0.05 significance level. Give the value of p you find to two decimal places, and choose the correct concdusion: Conclusion: A. Reject the null hypothesis B. Do not reject the null hypothesis
