Assume the average selling price for houses in a certain county is

$279,000

with a standard deviation of

$36,000.

a) Determine the coefficient of variation.b) Caculate the z-score for a house that sells for

$296,000.

c) Using the Empirical Rule, determine the range of prices that includes

68%

of the homes around the mean.d) Using Chebychev's Theorem, determine the range of prices that includes at least

89%

of the homes around the mean.
