Size of Homes in Two Subdivisions Subdivision Square Footage 2 Greenwood 2, 650 2, 792 2, 780 2, 363 2, 818 2, 781 2, 726 2, 371 2, 421 points Pinewood 2, 322 2, 413 2, 464 2, 475 2, 510 2, 796 2, 873 2, 551 3,940 Click here for the Excel Data File Book (a) Choose the appropriate hypothesis to test if there is a difference between the average sizes of homes in the two neighborhoods at the .10 significance level. Assume M1 is the mean of home sizes in Greenwood and M2 is the mean of home sizes in Pinewood. References a. Ho: M1 - H2 = 0 vs. H1: M1- M2 # 0 b. Ho: H1 - H2 # O vs. H1: H1 - M2 = 0 O a Ob (b) Specify the decision rule with respect to the p-value. Reject the null hypothesis if the p-value is ( less than 9 .10. (c) Find the test statistic tcalc. (A negative value should be indicated by a minus sign. Round your answer to 3 decimal places.) tcalc (d) Assume unequal variances to find the p-value. (Use the quick rule to determine degrees of freedom. Round your answer to 4 decimal places.) p-value (e) Make a decision. We do not reject the null hypothesis.
