Assume the average selling price for houses in a certain county is $295,000 with a standard deviation of $46,000 a) Determine the coefficient of variation b) Caculate the z-score for a house that sells for $275,000 c) Using the Empirical Rule, determine the range of prices that includes 95% of the homes around the mean d) Using Chebychev's Theorem, determine the range of prices that includes at least 91% of the homes around the mean HEBBE a) Determine the coefficient of variation cv = % (Round to one decimal place as needed) b) Calculate the Z-score for a house that sells for $275,000 (Round to two decimal places as needed) Z= c) Using the Empirical Rule, determine the range of prices that includes 95% of the homes around the mean upper bound x = $ lower bound x= S "(Round to the nearest dollar as needed) d) Using Chebycher's Theorem, determine the range of prices that includes at least 91% of the homes around the mean upper bound x = $ lower bound x = $ (Round to the nearest dollar as needed.)
