Ahmad was conducting some tests to determine if there was a relationship
between taking sleeping pills and the amount of sleep a person gets. His null
hypothesis was that taking sleeping pills did not have any effect on the
amount of sleep a person receives. Ahmad's alternate hypothesis was that
taking sleeping pills increases the amount of sleep a person will get.
If Ahmad completed his study, which of the following statements
would indicate a Type II error?
Type I and Type II Errors
Gaurav was conducting a test to determine if the average amount of
medication his patients were taking was similar to the national average. He
wants to use a 5% significance level for his test to help ensure that his
patients do not receive too little or too much medication.
If Gaurav were to conduct a test, what probability value would
indicate that his null hypothesis (that there is no significant
difference between the amount of medication Gaurav's patients are
receiving and the national average) would be rejected?
