For this case we want to test if  there is any difference in the mean prices of midrange homes of the two cities so then the system of hypothesis are:

Null hypothesis:

Alternative hypothesis:

And the best option for this case would be:

e. μ1 - μ2 = 0

And we can test the hypothesis using a two sample t test for the means

Step-by-step explanation:

For this case we have the following info given:

represent the sample mean for Evansville

represent the sample deviation

represent the sample size for Evansville
