Use the data to develop a 98% confidence interval for difference between the mean height of supermodels and mean height of women who aren't supermodels. Date: Supermodels have mean height of 70.0 inches with standard deviation of 1.5. Non-supermodel mean height is 63.2 inches with standard deviation of 2.7 inches (if required 0.01 is the significance level to be used). What does the result suggest about the two means?
