Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A researcher claims that at least 82% of people had at least one health care visit in the past year. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim does not contain a statement of equality, it represents the v hypothesis (a) How should you interpret a decision that rejects the null hypothesis? There is v evidence to v the claim that at least 82% of people had at least one health care visit in the past year. (b) How should you interpret a decision that fails to reject the null hypothesis? There is v evidence to V the claim that at least 82% of people had at least one health care visit in the past year

Which of the following is a true statement? a.Hypothesis tests are designed to measure the strength of evidence against the null hypothesis. b.A well-planned hypothesis test should result in a statement either that the null hypothesis is true or that it is false. c.When the null hypothesis is rejected, it is because it is not true. d.The alternative hypothesis is stated in terms of a sample statistic. e.If a sample is large enough, the necessity for it to be a simple random sample is diminished.
Which of the following statements are TRUE? I. Increasing the significance level of a test will increase the chance of erroneously rejecting a true null hypothesis. II. Increasing the significance level of a test will increase the chance of erroneously failing to reject a false null hypothesis. Only statement I is true. Neither statement is true. Only statement II is true. Both statements are true.
Which one of the following statements about the Type I error of hypothesis testing is wrong? a.It means that we may reject the null hypothesis H0 when H0 is actually true. b.It is closely related to the significance level of the test. c.Researchers can control the probability of Type I error. d.It means that we may fail to reject the null hypothesis H0 when H1 is true.
The claim that is assumed to be true in a hypothesis test is called: the power. the p-value. the alternative hypothesis. the null hypothesis.
A box model is used to conduct a hypothesis test for the following scenario: A marketing firm randomly selects 500 households in a town asking about their annual income. They want to test whether the percentage of households in town that have annual income above $100,000 is 50%. The SD of the ticket values in the box assuming the null hypothesis is true is best described as... a. Random and unknown; it must be estimated b. Fixed and unknown; it must be estimated c. Random and known d. Fixed and known
A claim is made that the proportion of college students who have Netflix accounts is 0.92. Mateo believes this claimed value is too high. He is able to survey a random sample of 180 college students, and he finds that the sample proportion who have Netflix accounts is 0.88. Mateo proceeds to use this data to conduct a hypothesis test. Based on this information, which one of the following statements is correct? The P-value will be smaller than 0.01 but larger than 0. The P-value will be between 0.01 and 0.05. The P-value will be between 0.05 and 0.10. The P-value will be larger than 0.10. The P-value will be negative.
Find the P -value for the indicated hypothesis test. A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 120 of the school's students, 30% of them plan to go into general practice. Find the P -value for a test of the school's claim.
