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 0.01 significance level. Compare the sample mean to the claimed mean of 34 minutes. Is the difference between those two values statistically significant?
