Question 1197893: In the country of United States of Height, the height measurements of ten-year-old children are approximately normally distributed with a mean of 55.7 inches, and standard deviation of 8.9 inches.
What is the probability that the height of a randomly chosen child is between 65.45 and 73.55 inches? Do not round until you get your your final answer, and then round to 3 decimal places.
Answer=
(Round your answer to 3 decimal places.)

You can put this solution on YOUR website! Normal Distribution: µ = 55.7 and σ = 8.9
Using hand-held TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
p( 65.45 ≤ x ≤ 73.55) = normcdf(65.45, 73.55, 55.7, 8.9) = .114 (Rounded to 3 decimal places.)
