**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.

The personality characteristics of business leaders (e.g., CEOS) are related to the operations of the businesses that they lead (Oreg & Berson, 2018). Traits like openness to experience are related to positive financial outcomes and other traits are related to negative financial outcomes for their businesses. Suppose that a board of directors is interested in evaluating the personality of their leadership. Among a sample of n = 16 managers, the sample mean of the openness to experiences dimension of personality was M = 4.50. Assuming that u = 4.24 and o = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with a = .05 to test the hypothesis that this company's business leaders' openness to experience is different from the population.

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.
