The accompanying data file shows the annual expenditures (in $) for 100 Amazon prime customers. picture Click here for the Excel Data File a. Construct a boxplot for the annual expenditures variable. Does the boxplot suggest that outliers exist? O No outliers exist. An outlier exists in the upper part of the distribution. An outlier exists in the lower part of the distribution. Outliers exist in both the lower and upper part of the distribution. b-1. Use z-scores to determine if there are any outliers for the annual expenditures variable. (Round final answers to 2 decimal places. Negative amounts should be indicated by a minus sign.) z-score for the smallest observation Z-score for the largest observation b-2. The Z-scores for the minimum and maximum observations suggest that: O no outliers exist. O an outlier exists in the upper part of the distribution. O an outlier exists in the lower part of the distribution. O outliers exist in both the lower and upper part of the distribution. b-3. Which of the following statements is most accurate with respect to outliers in this example? The boxplot and zscores provide consistent results. The boxplot is more reliable because the distribution is not symmetric. The zscores are more reliable because the distribution is not symmetric. The zscores are more reliable because the distribution is symmetric. 100% 26 EST COOT 0331 0301 C 1981 SEST PPT LEHT PCPT V 16 16 90 5231 ESIT UIT BIT CTT COET CEST JUT H BE TU BK 22 PET 90 COFT ET ISET SCOT CST za 72!
