Problem 23BSC

Standard Normal Distribution. In Exercises, assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. In each case, draw a graph and find the probability of the given scores. If using technology instead of Table, round answers to four decimal places.

Greater than –1.50

Step-by-Step Solution:

Step 1 of 1 :

In finding the area under the standard normal curve,we can use the statistical tables at the black of your textbook or use your calculator.

In using the tables,remember this the area are reported as P(z <  x)

Then,

P(z  > x) = 1- p(z < x)

P(a < z  < b) = p ( z < b) - p( z < a )

Applying this principle.

We assume that a randomly selected subject is given a bone density test.

Those test scores are normally distributed with a mean...
