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. 1212, 1818, 2323, 1414, 1515, 1818, 1919, 1616, 1313, 1616 The range is 1111. (Simplify your answer.) The mean is 16.416.4. (Simplify your answer. Round to the nearest tenth as needed.) The variance is nothing. (Simplify your answer. Round to the nearest hundredth as needed.) The standard deviation is nothing. (Simplify your answer. Round to the nearest tenth as needed.)
