Nine homes are chosen at random from real estate listings in two suburban neighborhoods, and the square footage of each home is noted in the following table. Size of Homes in Two Subdivisions Square Footage Subdivision Greenwood 2,309 2,726 2,725 2,878 2,427 2,666 2,737 2,885 2,544 Pinewood 2,871 2,675 2,803 2,629 2,749 2,888 2,340 2,684 3,888 B Click here for the Excel Data File (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.
