The accompanying data file shows the average monthly debt payments (Debt in $) for residents of 26 metropolitan areas. a. Construct a boxplot for the Debt variable. Does the boxplot suggest that outliers exist? Answer The boxplot suggests that there are no outliers for the Debt variable. b. Use z-scores to determine if there are any outliers for the Debt variable. Are your results consistent with part a? Explain why or why not. Answer x = 983.4615; s = 124.6086. The smallest and the largest observations for the Debt variable are 763 and 1,285, respectively. The z-score for the smallest observation is 763 - 983.4615 Z = = -1.7692 124.6086 The z-score for the largest observation is 1,285 - 983.4615 Z = = 2.4199 124.6086 Since the absolute value of both z-scores is less than 3, we conclude that there are no outliers for the Debt variable. This is consistent with the boxplot, which showed no outliers
