Question

A manufacturer knows that their items have a normally distributed length, with a mean of 17 inches, and standard deviation of 5.4 inches.

If one item is chosen at random, what is the probability that it is less than 4.8 inches long?

Expert Solution

Step 1

Let X be the length of the item.

We have, $μ = 17, σ = 5.4$

We want to find out P(X<4.8)

when X=4.8,

$Z = \frac{X - μ}{σ}, B y a p p l y i n g t h e a p p r o p r i a t e v a l u e s Z = \frac{4.8 - 17}{5.4} = - 2.2592$
