Use the accompanying 200 Los Angeles commute times to test the claim that the mean Los Angeles commute time is less than 34 minutes. Assume that a simple random sample has been selected. Use a 0.05 significance level. Compare the sample mean to the claimed mean of 34 minutes. Is the difference between those two values statistically significant? (Just need help with the last part of D...THE SAMPLE MEAN PORTION. Round to one decimal place as needed

A. Identify the null and alternative hypotheses .

Ho: u = 34

H1: u < 34

B. Test statistic

-1.07

C. P-value

0.143

D. Fail to reject the null hypothesis. There is not sufficient evidence at the 0.05 significance level to support the claim that the mean Los Angeles commute time is less than 34 minutes.

The sample mean is ? minut(s) less/greater than the claimed mean of 34 minutes: this difference is/is not statistically significantly by the standard of this test.
