Scott: Xbar = $123, 430 standard deviation = 3702 n = 25 a. What interval method will you use to create your interval and why? b. Create a 95% confidence interval. ( c. Create a hypothesis test at alpha = 0.05 testing the claim that the average cost of a home in Scott Township is different than the average population price in PA. Do you accept or reject the null hypothesis? *State the null and alternative hypothesis. *Calculate the test statistic *Draw the normal curve with boundary values for the one or two sided test.
