Question 1179295: In the country of United States of Heightlandia, the height measurements of ten-year-old children are approximately normally distributed with a mean of 54.9 inches, and standard deviation of 3.9 inches.
What is the probability that the height of a randomly chosen child is between 57.65 and 63.05 inches? Do not round until you get your your final answer, and then round to 3 decimal places.
Hi
Distribution: normal with µ = 54.9 and σ = 3.9
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
SELECT ONE:
P( 57.65< x < 63.05) = normalcdf(57.65,63.05,54.9,3.9) = .222
Wish You the Best in your Studies.
