Many families in California are using backyard structures for home offices, art studios, and hobby areas as well as for additional storage. Suppose that the mean price for a customized wooden, shingled backyard structure is $3,400. Assume that the standard deviation is $1,200. (a) What is the z-score for a backyard structure costing $2,400? (Round your answer to two decimal places.) (b) What is the z-score for a backyard structure costing $5,2007 (c) Interpret the z-scores in parts (a) and (b). Comment on whether either should be considered an outlier. The cost $2,400 is 0.83 standard deviations below the mean, therefore it is not an outlier o . The cost $5,200 is 1.50 standard deviations below * the mean, therefore it is an outlier o % . (d) The cost for a backyard shed-office combination built in Albany, California, is $14,500. Compute the z-score for this structure. 2 Should this structure be considered an outlier? Explain. This structure is not an outlier o >
