2] Sample of residential lot sizes in meters squared of residential properties for sale January 10, 2010 in Toronto and Vancouver. Determine if there is a significant difference in the lot sizes for the residential properties for sale.

Step 1:

d=before-after

Let µd be the population mean difference in the lot sizes in square meters of residential properties for sale January 10, 2010 in Toronto and Vancouver.

Step 2:

H0: µd = 0

HA: µd ≠ 0

Step 3:

Level of significance: 0.05

Step 4:

Paired observation mean t- test

Step 5:

tStatistic: -15.991

tCritical: 1.684

p-value:

degree of freedom: 44

Step 6:

Since the p-value < 0.05, reject the null hypothesis. There is enough evidence to conclude that there is a significant difference in the lot sizes in square meters of residential properties for sale January 10, 2010 in Toronto and Vancouver.
