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.
Less than 2.33
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 less than 2.33.
The type of test is determined by the Alternative Hypothesis ( H1 ):
Left tailed test:
parameter < value.
Decision rule: Reject H0 if test statistic. < critical value.
