2. The Eagle Ridge Contractors Association claims an average price of a home in their subdivision is $125,150 with a standard deviation of $7,350. A sample of 36 homes for sale in this subdivision had an average selling price of $123,550. Is there evidence that the costs of homes for sale in this subdivision are actually lower than claimed?

What is the p-value for a one-sided test of the data provided above?

i) 0.0036

ii) 0.1327

iii) 0.0853
