O A. Data set (ii), because it has two entries that are far away from the mean. O B. Data set (iii), because it has more entries that are farther away from the mean. O C. Data set (i), because it has more entries that are close to the mean. Which data set has the least sample standard deviation? O A. Data set (iii), because it has more entries that are farther away from the mean. O B. Data set (ii), because it has less entries that are farther away from the mean. O C. Data set (i), because it has more entries that are close to the mean. (b) How are the data sets the same? How do they differ? O A. The three data sets have the same mode but have different standard deviations and means. O B. The three data sets have the same mean, median and mode but have different standard deviations. O C. The three data sets have the same standard deviations but have different means. O D. The three data sets have the same mean and mode but have different medians and standard deviations.The ages (in years) of a random sample of shoppers at a gaming store are shown. Determine the range, mean, variance, and standard deviation of the sample data set. 12,18,23,14,1?,16,19,16,13,15 % The range is 11 . (Simplify your answer.) The mean is -. (Simplify your answer. Round to the nearest tenth as needed.) The variance is m. [Simplify your answer. Round to the nearest tenth as needed.) The standard deviation is . (Simplify your answer. Round to the nearest tenth as needed.)
