A)IQR: $789.3;standard deviation: $740 The IQR is the most appropriate measure of centre,because of the outliers.
B)IQR: $715;standard deviation: $769 The standard deviation is the most appropriate measure of centre,because of the outliers.
C)IQR: $715;standard deviation: $769 The standard deviation is the most appropriate measure of centre,because the outliers are not significant in the distribution.
D)IQR: $715;standard deviation: $769 The IQR is the most appropriate measure of centre,because the outliers are not significant in the distribution.
E)IQR: $715;standard deviation: $769 The IQR is the most appropriate measure of centre,because of the outliers.
