You decide to flip a coin each day to decide which route to take to school: highway or back roads. In a random sample of 15 days that you take the highway, the mean travel time was 22 minutes with a standard deviation of 4 minutes. In a random sample of 15 days that you take the back roads, the sample mean was 25 minutes with a standard deviation of 2 minutes. Assume that each sample is approximately normally distributed. a. Perform all 7 steps of hypothesis testing to determine if there is a difference in the mean travel time betweenthe two routes, at α = 0.05.b. Find and interpret a 95% confidence interval for the difference in two means. How large might the differencein means be?

A baseball team claims that the mean length of its games is 2.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≤2.4." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≠2.4." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 2.4 hours."
