Heights of 10 year-olds, regardless of gender, closely follow a normal distribution with mean 55 inches and standard deviation 6 inches. Which of the following is true? Roughly 95% of 10 year-olds are between 37 and 73 inches tall. A 10 year-old who is 65 inches tall would be considered more unusual than a 10 year-old who is 45 inches tall. A normal probability plot of heights of a random sample of 500 10 year- olds people should show a fairly straight line. We would expect more 10 year-olds to be shorter than 55 inches than taller
