Use the P-value method to test the given hypothesis.

A nationwide study of American homeowners revealed that 64% have one or more lawn mowers. A lawn equipment manufacturer, located in Omaha, feels the estimate is too low for households in Omaha. Can the value 0.64 be rejected if a survey of 498 homes in Omaha yields 332 with one or more lawn mowers? Use = 0.05

A. There is sufficient evidence to support the claim that the proportion with lawn mowers in Omaha is 0.64.

B. There is not sufficient evidence to warrant rejection of the claim that the proportion with lawn mowers in Omaha is 0.64.

C. There is sufficient evidence to warrant rejection of the claim that the proportion with lawn mowers in Omaha is 0.64.

D. There is not sufficient evidence to support the claim that the proportion with lawn mowers in Omaha is 0.64.

Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim.

A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO, p, is less than 2 in every ten thousand. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.

A. There is not sufficient evidence to support the claim that the true proportion is greater than 2 in ten thousand.

B. There is not sufficient evidence to support the claim that the true proportion is less than 2 in ten thousand.

C. There is sufficient evidence to support the claim that the true proportion is less than 2 in ten thousand.

D. There is sufficient evidence to support the claim that the true proportion is greater than 2 in ten thousand.

Assume that a hypothesis test of the given claim will be conducted. Identify the type I or type II error for the test.

The owner of a football team claims that the average attendance at games is over 74,500, and he is therefore justified in moving the team to a city with a larger stadium. Identify the type II error for the test.

A. The error of failing to reject the claim that the mean attendance is at most 74,500, when it is actually greater than 74,500.

B. The error of rejecting the claim that the mean attendance is at most 74,500, when it really is at most 74,500.

C. The error of failing to reject the claim that the mean attendance is more than 74,500, when it is actually less than 74,500.

State the decision rule to test the null hypothesis.

496 people were asked if they were satisfied with their jobs. 39% said they were. AlternativeHypothesis (H₁): p> 0.26. Confidence level: 98%.

A. RejectNull Hypothesis (H₀) ifthe test statistic is > 2.575.

B. RejectNull Hypothesis (H₀) ifthe test statistic is > 2.33.

C. RejectNull Hypothesis (H₀) ifthe test statistic is< 2.05.

D. RejectNull Hypothesis (H₀) ifthe test statistic is> 2.05.
