Question 5 (4 points) Saved Suppose you sample housing sale prices from North York and Markham. From the sample of 15 homes from North York, the mean is $615,000 and the standard deviation is $30,000.The sample of 15 homes from Markham has a mean of $655,000 and a standard deviation of $80,000. You want to test to see if Markham homes are more expensive than North York homes, on average. Answer the following questions in the blanks below. Use two decimal places. [4 points] 1.
