Question 1183691: Women’s shoes are manufactured in sizes 2, 3, 4, …, 8. Size 5 is suitable for a foot of length ranging from 9.25 inches to 9.5 inches. If length of women’s foot are normally distributed with mean 9.4 inches and standard deviation 0.25 inches, how many pairs of size 5 are required out of every 10,000 pairs manufactured? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! This is z=(x-mean)/sd
so z is between -0.15/0.25 or -0.6
and 0.1/0.25 or 0.4
That probability is 0.38117, and multiplied by 10000 is 3812, rounding up.
