Question: The property tax appraiser is concerned about possible horizontal inequity (equals not being treated equally) in two developments in West Dade. N for the first development is 15. X-bar (assessed value in thousands of dollars) is 285, s=14. For the second development, N = 11, X-bar is 272, s= 12.

i. Using a two-tailed analysis, a=.05, address the possibility that development one and two are being assessed differently. Set up the null, the alternative, and the appropriate critical t value before testing the hypothesis.
