Suppose the heights of 10 year old boys are normally distributed with a mean of 55.9 inches and a standard deviation of 5.7 inches? We can say that about 68% of 10 year old boys are between_____ and _____ inches tall. Round values 1 decimal place.

Boys Heights Heights of ten-year-old boys (5th graders) follow an approximate normal distribution with mean μ = 55.5 inches and standard deviation σ = 2.7 inches. (a) According to this normal distribution, what proportion of 10-year-old boys are between 4 ft 4.5 in and 5 ft 0.5 in tall (between 52.5 inches and 60.5 inches)? Round your answer to four decimal places.
