**Study on Incentives and Telephone Survey Response Rates**A research team (Singer et al., 2000) utilized the Survey of Consumer Attitudes to examine whether incentives could enhance the response rates for telephone surveys. They selected a national sample of 735 households, with each household receiving an "advance letter" to inform them of an upcoming survey. The households were divided into two groups: - 368 households were sent a monetary incentive along with the letter.- 367 households received only the letter, without an incentive.**Response Data**The table below provides data on the households' responses:| | Received an Incentive | | | |-----------------------|-----------------------|------------------|---|| | Yes | No | Total || **Responded to the telephone survey?** | | | || **Yes** | 286 | 245 | 531 || **No** | 82 | 122 | 204 || **Total** | 368 | 367 | 735 |**Analysis**- **With Incentive**: 286 households responded, and 82 did not respond.- **Without Incentive**: 245 households responded, while 122 did not respond.This data suggests that the inclusion of a monetary incentive may positively influence the likelihood of households participating in the survey. ### Transcript for Educational Website**e.** Did the study involve random *assignment* to either receive an incentive or not? If yes, what is the advantage? If no, what is the disadvantage?**f.** An appropriate analysis of the data shows there is evidence that people receiving an incentive are more likely to respond to the telephone survey compared to those receiving no incentive. Is it appropriate to conclude that incentives *improve* response rates? Why or why not? Explain your reasoning.

A survey was conducted to determine whether hours of sleep per night are independent of age. A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age 40 or older. Sample data follow.

A graduate student is interested in how viewing different types of scenes affects working memory. For his study, he selects a random sample of 36 adults. The subjects complete a series of working memory tests before and after walking in an urban setting. Before the walk, the mean score on the test of working memory was 9.1. After the walk, the mean score was 1.4 higher. The graduate student has no presupposed assumptions about how viewing different types of scenes affects working memory, so he formulates the null and alternative hypotheses as: H00 : μDD = 0 H11 : μDD ≠ 0 Assume that the data satisfy all of the required assumptions for a repeated-measures t test. The graduate student calculates the following statistics for his hypothesis test: Mean difference (MDD) 1.4 Estimated population standard deviation of the differences (s) 1.6 Estimated standard error of the mean differences (sMDMD) 0.2667 Degrees of freedom (df) 35 The t statistic 5.25 The critical values of t…
Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?

If sample data is such that for a one-tailed test of ? you can reject H0 at the 1% level of significance, can you always reject H0 for a two-tailed test at the same level of significance? Explain your answer? A. Yes. If H0 for a one-tailed test is rejected at the 1% level of significance, it will always be rejected for a two-tailed test at the same level of significance. B. No. If H0 for a one-tailed test is rejected at the 1% level of significance, it will never be rejected for a two-tailed test at the same level of significance. C. Yes. The P-value for the two-tailed test could be greater than 0.01. D. No. The P-value for the two-tailed test could be greater than 0.01.
Which summary statement best reflects the findings of the hypothesis test above. O The sample data suggests that happiness and technology use are dependent. The sample data suggests that the mean happiness scores of the the 3 technology groups are different. The sample data suggests that the mean happiness scores of the the 3 technology groups are not different. The sample data suggests that the proportion of happiness is the same for all technology groups.

K The concerns about the impact of technology on our lives are growing. There have been recent research reports about the negative impact of digital technology usage on stress, work productivity, happiness, and overall well-being. In light of these concems, a polling organization asked technology experts about their opinion on our digital life and found that 28% of the experts believe that in the future our lives will be more harmed than helped by their digital environment. In an effort to confirm these results, a local tech company decides to ask 210 randomly selected customers their opinions about their digital life. Answer parts a through c below. a.
