**Study on Incentives and Response Rates in Telephone Surveys**A team of researchers (Singer et al., 2000) conducted a study using the Survey of Consumer Attitudes to determine if incentives would enhance response rates in telephone surveys. A national sample of 735 households was selected for the study. All households received an "advance letter" explaining the upcoming phone survey. Out of these, 368 households were randomly chosen to receive a monetary incentive along with the letter, while the remaining 367 households received only the advance letter. The following data illustrates the response outcomes:| | **Received an Incentive?** | | ||--------------------------------|---------------------------|-------|-------|| **Responded to the telephone survey?** | **Yes** | **No** | **Total** || Yes | 286 | 245 | 531 || No | 82 | 122 | 204 || **Total** | 368 | 367 | 735 |**Explanation:**- **Incentive Group:** - 286 households responded to the survey. - 82 households did not respond. - **No Incentive Group:** - 245 households responded to the survey. - 122 households did not respond. In total, 531 households participated in the survey, while 204 did not. The study seeks to highlight the impact of incentives on participation rates in telephone surveys. **a.** Was this an observational study or an experiment?

Recent research has shown that creative people are more likely to cheat than their less-creative counterparts (Gino & Ariely, 2011). Participants in the study first completed creativity assessment questionnaires and then returned to the lab several days later for a series of tasks. One task was a multiple-choice general knowledge test for which the participants circled their answers on the test sheet. Afterward, they were asked to transfer their answers to a bubble sheet for computer scoring. However, the experimenter admitted that the wrong bubble sheet had been copied so that the correct answers were still faintly visible. Thus, the participants had an opportunity to cheat and inflate their test scores. Higher scores were valuable because participants were paid based on the number of correct answers. However, the researchers had secretly coded the original tests and the bubble sheets so that they could measure the degree of cheating for each participant. Assuming that the…
This experiment examines the performance, as measured by the number of errors made, on a motor skills task. 24 subjects, 12 young and 12 old, were assigned to either an easy or hard motor skills task. There were 2 factors in the study: age (young/old) and difficulty of the motor skills task (easy/hard). The number of errors made on the motor skills task was recorded for each person and is presented in the table below. Null and Alternative Hypotheses: H0: There is not an interaction between young and old H0: µYoung = µOld H1: There is an interaction between young and old H1: µYoung ≠ µOld H0: There is not an interaction between easy and hard H0: µEasy = µHard H1: There is an interaction between young and old H1: µEasy ≠ µHard H0: There is not an interaction between age and difficulty H0: µAge = µDifficulty H1: There is an interaction between age and difficulty. H1: µAge ≠ µDifficulty My question: Report the results of the hypothesis tests below. Be sure to express the results in the…
A Michigan study concerning preference for outdoor activities used a questionnaire with a six-point Likert-type response in which 1 designated "not important" and 6 designated "extremely important." A random sample of n1 = 45 adults were asked about fishing as an outdoor activity. The mean response was x1 = 4.9. Another random sample of n2 = 55 adults were asked about camping as an outdoor activity. For this group, the mean response was x2 = 4.0. From previous studies, it is known that σ1 = 1.5 and σ2 = 2.0. Does this indicate a difference (either way) regarding preference for camping versus preference for fishing as an outdoor activity? Use a 5% level of significance. Note: A Likert scale usually has to do with approval of or agreement with a statement in a questionnaire. For example, respondents are asked to indicate whether they "strongly agree," "agree," "disagree," or "strongly disagree" with the statement. (a) What is the level of significance? What is the value of the sample…
A Michigan study concerning preference for outdoor activities used a questionnaire with a six-point Likert-type response in which 1 designated "not important" and 6 designated "extremely important." A random sample of n1 = 44 adults were asked about fishing as an outdoor activity. The mean response was x1 = 4.9. Another random sample of n2 = 47 adults were asked about camping as an outdoor activity. For this group, the mean response was x2 = 5.6. From previous studies, it is known that σ1 = 1.2 and σ2 = 2.0. Does this indicate a difference (either way) regarding preference for camping versus preference for fishing as an outdoor activity? Use a 5% level of significance. 1. What is the value of the sample test statistic? (Test the difference μ1 − μ2. Round your answer to two decimal places.) 2. Find (or estimate) the P-value. (Round your answer to four decimal places.)
For a certain year, a study reports that the percentage of college students using credit cards was 87%. A college dean of student services feels that this is too high for her university, so she randomly selects 225 students and finds that 190 of them use credit cards. At the .01 significance level, is she correct about her university?
7.71 TV subscription streaming. "Streaming" of television pro- grams is trending upward. According to The Harris Poll (August 26, 2013), over one-third of American's qualify as "subscription streamers," i.e., those who watch streamed TV programs through a subscription service such as Netflix, Hulu Plus, or Amazon Prime. The poll included 2,242 adult TV viewers, of which 785 are subscription streamers. On the basis of this result, can you conclude that the true fraction of adult TV viewers who are subscription streamers differs from one-third? Carry out the test using a Type I error rate of a = .10. Be sure to give the null and alternative hypotheses tested, test statistic value, rejection region or p-value, and conclusion.
In a recent survey, 10% of the participants related Pepsi as being "concerned with my health." PepsiCo's response included a new "Smart Spot" symbol on its products that meet certain nutrition criteria to help consumers who seek more healthy eating options. At a = .05, would a follow-up survey showing that 18 or 100 persons now rate Pepsi as being "concerned with my health" provide sufficient evidence that the percentage has increased?

To test the fairness of law enforcement in its area, a local citizens' group wants to know whether women and men are unequally likely to get speeding tickets. Four hundred randomly selected adults were phoned and asked whether or not they had been cited for speeding in the last year. Using the results in the following table and a 0.05 level of significance, test the claim of the citizens' group. Let men be Population 1 and let women be Population 2. Speeding Tickets Ticketed Not Ticketed Men 26 191 Women 10 173 Copy Data Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.
The effects of social skill training on a 29 year-old mentally retarded male adult were explored. The subject listened to typical social situations (such as getting a compliment or saying thank you) on audiotape and discussed the situations with a therapist. The subject's positive social verbal interactions were counted before the training, at three times during the training period, and at three times after the training had been completed. All counts were taken by observing the subject at a evening recreation time in the subject's group home. Results show that positive interactions increased during the training period but then rapidly decreased after training had stopped.
