Question

Assume the average selling price for houses in a certain county is $368,000 with a standard deviation of $43,000. a) Determine the coefficient of variation. b) Caculate the z-score for a house that sells for $357,000. 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 84% of the homes around the mean. a) Determine the coefficient of variation. CV = 11.7 % (Round to one decimal place as needed.) b) Calculate the z-score for a house that sells for $357,000. z = - .26 (Round to two decimal places as needed.) c) Using the Empirical Rule, determine the range of prices that includes 68% of the homes around the mean. upper bound x = $ 411000 lower bound x = $ 325000 (Round to the nearest dollar as needed.) d) Using Chebychev's Theorem, determine the range of prices that includes at least 84% of the homes around the mean. upper bound x = $ lower bound x = $ (Round to the nearest dollar as needed.)
