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 0.82

Answer:

Step 1:

Assume that a randomly selected subject is given a bone density. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1.

Given the probability of score is greater than 0.82.

The type of test is determined by the Alternative Hypothesis ( H1 ):

Right tailed test:

parameter > value.

Decision rule: Reject H0 if test statistic. > critical value.

The graph of area under normal curve is given below:
