- Epatol A group of researchers wanted to examine some hypotheses about the behavior of people who bet on professional football games. One hypothesis was that people tend to bet according to how their picks turned out the previcus week: if the team a person picked to win one week actually won, the person might also pick that team the next week, thinking that the team is "on a hot streak," or the person might bet against that team the nexct week, thinking that the team is "due for a loss." Anather hypothesis was that there is no such rhyme or reason to betting: there is no association between the bets that people make one week and the bets they make the next. In an experimental study, the researchers had each of their participants bet on each game of a professional football season. The contincency table below contains some information from a random sample of 100 bets placed on the Columbus Crush (picking them to win) during the last 14 games of the season (the Crush had 7 wins and 7…The power of a test is the probability that it will a) reject a true null hypothesis. b) reject a false null hypothesis. c) fail to reject a true null hypothesis. d) fail to reject a false null hypothesis.Claim: A minority of adults would erase all of their personal information online if they could.

- In a recent study, 20 males used a new weight-loss supplement, and all but 4 of them experienced weight loss after two weeks. In the same study, 100 females used the same supplement, and all but 13 of them experienced weight loss after two weeks. Fill in the blanks of the statement below to make the statement the most reasonable possible. The new weight-loss supplement was less effective on ? in the study because ? % of them failed to lose weight after two weeks, whereas only ? % of the ? failed to lose weight after two weeks.SpAt most 90% of people support the death penalty.

- A researcher is interested in whether people are more or less likely to enjoy popcorn when they are watching TV versus watching a movie. The researcher recruits 12 participants and randomly assigns them to eat popcorn either while watching T or while watching a movie. Then, the researcher measures now much each participant enjoyed the popcorn on a scale from 1 to 10. The researchers' results are shown below: Using the appropriate hypothesis test and the six steps of hypothesis testing, see what the researcher should conclude about the effect of watching television versus watching a movie on people's enjoyment of popcorn. Construct a sampling distribution of means representing the null hypothesis. Specify the sampling distribution's mean and standard error 5. Using a two-tailed alpha of .05 (a = .05), determine the critical values 6. Calculate the test statistic 7. State whether you reject or fail to reject the null hypothesis 8. Calculate and report a measure of effect size . 9. Based…A highly selective MBA program wants their students' average score on the GMAT exam to be greater than 650.
