Question 229088
"Does the average selling price of a home with a pool differ fom the average selling price of a home without a pool? 
(a) Formulate both verbal and numerical and verbal statement. 
(b) Perform the five step hypothesis test on data.
Ho: u(pool)-u(no pool) = 0
Ha: u(pool)-u(no pool) is not 0
---
I ran a 2-Sample T-test on a TI calculator and got the following results:
test statistic: t = 3.502
p-value = 0.0006923... 
 
(c) Describe the results and explain how you got the result.
Since the p-value is less than 1% reject Ho at the 1% significance
level.  The selling price for the two classes of homes is different.

--------------------------------------------------------------------- 
Home without pool has N = 67 x-bar = 231.49 and s = 50.57
------
Home with pool has N = 38 x-bar = 202.60 s = 33.71
