Chapter 10: Problem 16

A television station has been providing live coverage of a sensational criminal trial. The station's program director wants to know if more than half of potential viewers prefer a return to regular daytime programming. A survey of randomly selected viewers is conducted. With \(p\) representing the proportion of all viewers who prefer regular daytime programming, what hypotheses should the program director test?

Short Answer

Expert verified
Null hypothesis (\(H_0\)): \(p = 0.5\) (half of the viewers prefer regular daytime programming). Alternative hypothesis (\(H_1\)): \(p > 0.5\) (more than half of the viewers prefer regular daytime programming).

Step by step solution

01

Formulate the Null Hypothesis (\(H_0\))

In hypothesis testing, the Null Hypothesis (\(H_0\)) typically proposes a general or default position. In this scenario, the null hypothesis can be formulated as: \(H_0\): \(p = 0.5\). This means that half of the viewers prefer regular daytime programming.
02

Formulate the Alternative Hypothesis (\(H_1\))

The Alternative Hypothesis (\(H_1\)) is usually what the researcher wants to prove. It is a statement that contradicts the null hypothesis. In this situation, the program director wants to know if more than half of the potential viewers prefer regular daytime programming. Thus, the alternative hypothesis is: \(H_1\): \(p > 0.5\). This means that more than half of the viewers prefer regular daytime programming.

An automobile manufacturer is considering using robots for part of its assembly process. Converting to robots is expensive, so it will be done only if there is strong evidence that the proportion of defective installations is less for the robots than for human assemblers. Let \(p\) denote the actual proportion of defective installations for the robots. It is known that the proportion of defective installations for human assemblers is 0.02 . a. Which of the following pairs of hypotheses should the manufacturer test? $$H_{0}: p=0.02 \text { versus } H_{a}: p<0.02$$ or $$H_{0}: p=0.02 \text { versus } H_{a}: p>0.02$$ Explain your choice. b. In the context of this exercise, describe Type I and Type II errors. c. Would you prefer a test with \(\alpha=0.01\) or \(\alpha=0.10 ?\) Explain your reasoning.

The report "2007 Electronic Monitoring and Surveillance Survey: Many Companies Monitoring, Recording, Videotaping-and Firing-Employees" (American Management Association, 2007) summarized a survey of 304 U.S. businesses. Of these companies, 201 indicated that they monitor employees' web site visits. Assume that it is reasonable to regard this sample as representative of businesses in the United States. a. Is there sufficient evidence to conclude that more than \(75 \%\) of U.S. businesses monitor employees' web site visits? Test the appropriate hypotheses using a significance level of 0.01 . b. Is there sufficient evidence to conclude that a majority of U.S. businesses monitor employees' web site visits? Test the appropriate hypotheses using a significance level of 0.01 .

In a survey of 1,000 women ages 22 to 35 who work full-time, 540 indicated that they would be willing to give up some personal time in order to make more money (USA Today, March 4, 2010). The sample was selected to be representative of women in the targeted age group. a. Do the sample data provide convincing evidence that a majority of women ages 22 to 35 who work fulltime would be willing to give up some personal time for more money? Test the relevant hypotheses using \(\alpha=0.01\) b. Would it be reasonable to generalize the conclusion from Part (a) to all working women? Explain why or why not.

For which of the following \(P\) -values will the null hypothesis be rejected when performing a test with a significance level of \(0.05 ?\) a. 0.001 d. 0.047 b. 0.021 e. 0.148 c. 0.078

Duck hunting in populated areas faces opposition on the basis of safety and environmental issues. In a survey to assess public opinion regarding duck hunting on Morro Bay (located along the central coast of California), a random sample of 750 local residents included 560 who strongly opposed hunting on the bay. Does this sample provide convincing evidence that a majority of local residents oppose hunting on Morro Bay? Test the relevant hypotheses using \(\alpha=0.01\).
