Show steps in Excel for all. a What is the z-score for a backyard structure costing $2300? b What is the z-score for a backyard structure costing $4900 c Interpret the z-scores in parts (a) and (b). Comment on whether either should be considered an outlier. d If the cost for a backyard shed-office combination built in Albany, California is $13000, should the structure be considered an outlier? Explain.
