Question

Using the data in Exercise 3, test the hypothesis that the mean age of houses in the two neighborhoods is the same. You may assume that the ages of houses in each neighborhood follow a Normal distribution.
a) Calculate the P-value of the statistic knowing that the approximation formula gives 62.2 df (you will need to round or use technology).
b) Calculate the P-value of the statistic using the rule that df is at least min (n1 – 1, n2 – 1).
c) What do you conclude at α = 0.05?
