You have downloaded the MS_Excel file with data on the prices of homes in two neighborhoods around the City of New York. The data is taken from Staten Island.
Using the MS_Excel, calculate:
a. The Average and the Standard Deviation for Sale Price for houses in the two neighborhoods
b. The Average and the Standard Deviation for Sale Price Per Square Foot for houses in the two neighborhoods
c. The Average and the Standard Deviation for Age of houses in the two neighborhoods. Please note that you must calculate the Age of each house sold. Take note also that all houses were sold in 2009.
d. Present you results on the Averages in tables and a charts.
e. List at least four reasons that you think that the Average price of houses in one neighborhood will be different from the other neighborhood.
a. b. and c. are:
For mean, function = average()
For standard deviation, function = stdev.p()
