Question

4. The campaign manager for a congressional candidate claims that the candidate has more than 50% support from the district's electorate. A newspaper collects a simple random sample of 500 likely voters in this district and estimates the support for this candidate to be 52%. The p-value for the hypothesis test evaluating the campaign manager's claim is 0.19. Which of the below is correct? If in fact 50% of likely voters support this candidate, the probability of obtaining a random sample of 500 likely voters where 52% or more support the candidate is 0.19. 95% of random samples of size 500 will estimate the support for this candidate to be 52%. The success-failure condition is not met, so this p-value is not reliable. The data provide convincing evidence for the campaign manager's claim. 6. To evaluate the following hypotheses H0 :p = 0.3 HA :p ? 0.3 we use a random sample of 50 observations where p? = 0.36. Which of the following is the correct standard error? Choose the closest answer. 0.0096 0.0297 0.0679 0.0042 0.0092 0.0648 12. Does Weight Watchers work? Researchers randomly divided 500 people into two equal-sized groups. One group spent 6 months on the Weight Watchers program. The other group received a pamphlet about controlling portion sizes. At the end of the study 35% of the subjects in the pamphlet group and 55% of the subjects in the Weight Watchers group had lost at least 10 pounds. To test whether Weight Watchers is more effective for weight loss than pamphlets, a statistician used an index card to represent each subject in the study and wrote whether or not the subject lost at least 10 pounds on the index card. He then shuffled these cards together, and dealt them into two equal-sized groups. Which of the following best describes the expected result? The difference between the proportions of cards indicating whether or not the subject lost at least 10 pounds will be about 20%. If Weight Watchers was effective, the difference between the proportions of cards indicating whether or not the subject lost at least 10 pounds will be more than 20%. The difference between the proportions of cards indicating whether or not the subject lost at least 10 pounds will be about 0.
