The average sales price of new one-family houses in the Midwest is $252,400 and in the South is $259,500. A random sample of 36 houses in each region was examined with the following results. At the 0.05 level of significance, can it be concluded that the difference in mean sales price for the two regions is greater than $3400? Midwest South Sample size 36 36 Sample...
