kIf a random sample of 20 homes south of a town has a mean selling price of $145,075 and a standard deviation of $4850, and a random sample of 24 homes north of a town has a mean selling price of $148,300 and a standard deviation of $5750, can you conclude that there is a significant difference between the selling price of homes in these two areas of the town at the 0.05 level? Assume normality. (a) Find t. (Round your answer to two decimal places.) (ii) Find the p-value.

It has been suggested that residents in the rural areas of the South have a different life-span than in the North. In a random sample of 50 residents of the rural South, the mean life span was 75.9 with a sample standard deviation of 9.8. A random sample of 75 residents of the North, the mean life span was 82.4 with a sample standard deviation of 6.1. Is the sample evidence strong enough to claim that those in the South...
