Find the mean and standard deviation for the following sample data. Then calculate the range where you would expect to find 95% of the data points based on the empirical rule. Set D: 22,18,18,16,23,19,18,15,21,17,16,20,17,16,20,17,29,23,26,15,14,21,13,20,17,17,13,24,23 Count how many of the data points actually fall within the range. What is the percentage based on data set? Does […]
