9.Compare the standard deviation for the heights of males and the standard deviation for the heights of females in the class. Compare the values and explain what can be concluded based on the numbers.
Compare the mean for the heights of males and the mean of the heights of females in the following data. Compare the values and explain what can be concluded based on the numbers.male- 66, 69, 71, 74, 73, 61, 69, 71, 74female - 67, 64, 67, 70, 66, 69, 65, 70, 63, 70, 69
-Using the empirical rule, 95% of female heights should be between what two values? Either show work or explain how your answer was calculated.- Using the empirical rule, 68% of male heights shoul be betweeen what two values? Either show work or explain how your answer was calculated.
