Question
Occasionally, warning flares of the type contained in most automobile emergency kits fail to ignite. A consumer advocacy group wants to investigate a claim against a manufacturer of flares brought by a person who claims that the proportion of defective flares is much higher than the value of .1 claimed by the manufacturer. A large number of flares will be tested, and the results will be used to decide between H0: p = .1 and Ha: p > .1, where p represents the proportion of defective flares made by this manufacturer. If H0 is rejected, charges of false advertising will be filed against the manufacturer.
(a) Explain why the alternative hypothesis was chosen to be Ha: p > .1.
The alternative hypothesis was chosen to help with filing charges against the manufacturer.
The alternative hypothesis was chosen because the true proportion of defective flares is more than .1.
The alternative hypothesis was chosen arbitrarily.
The alternative hypothesis was chosen because people wanted to know whether the proportion of defective flares exceeds .1. No one would mind if the proportion of defective flares was less than .1.
(b) In this context, describe a Type I error, and discuss the consequences.
A Type I error would be the conclusion that the proportion of defective flares is 10% when, in reality, the proportion is in excess of 10%. The consequence of this decision is to allow the manufacturer who is guilty of false advertising to continue bilking the consumer.
