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?
Did I calculate this correctly? Thank you.

The weekly expenditure on groceries of a random sample of 100 family households was recorded. It was estimated that the mean expenditure was approximately $240. With rising interest rates and petrol prices, it was anticipated that grocery expenditure might decrease. Which hypothesis test would you use to test this claim? 1.One tailed, one sample t-test 2.Two tailed, one sample t-test 3.One tailed, z-test 4.One-tailed Paired Samples t-test 5.Chi Square
State the null and alternate hypothesis. Will you use a left tail, right tail or 2 tailed test? Identify the sampling distribution to be used: standard normal, Student’s t or chi squared. Find the value of the test statistic. Find the P-Value. Based on your answers, shall we reject or accept the null hypothesis? Write the conclusion in the context of the problem.
