3. Find the standard deviation using the following numbers Number Mean 36 40 45 Number - mean 61 10. Draw a normal curve with μ = 110 and a = 5. Sum (E): Square Divide, then square root. The standard deviation (a) = 9. In all the boys of the school, the height of the boys are normally distributed with a mean of 68 inches and a standard deviation of 2.5 inches. Using the empirical rule, determine the interval of heights that represents the middle 95% of the male heights from the school. a) What percentage is between 110 and 115? b) What interval represents 95%? c) What interval represents 99.7%?
