Corporate sustainability of CPA firms. Corporate sustainability refers to business practices designed around social and environmental considerations. Refer to the Business and Society (March 2011) study on the sustainability behaviors of CPA corporations, Exercise 2.23 (p. 59). Recall that the level of support for corporate sustainability (measured on a quantitative scale
- a. Locate the 90% confidence interval on the printout.
- b. Use the sample mean and standard deviation on the printout to calculate the 90% confidence interval. Does your result agree with the interval shown on the printout?
- c. Give a practical interpretation of the 90% confidence interval.

- Which of these is a question that would require a z test? Question 31 options: Does a sample of couples who communicate primarily by texting have a higher relationship satisfaction than that of a sample of couples who communicate primarily by phone? Does a sample of nurses in large hospitals get sick more often than a sample of nurses in smaller hospitals? Does a sample of people from rural communities have different levels of social intelligence than a sample of people from urban centers? Does a sample of purebred dogs live longer than dogs in general?arrow_forwardMedical research has shown that repeated wrist extensions beyond 20 degrees increase the risk of wrist and hand injuries. Each of 24 students at Cornell University used a proposed new computer mouse design, and while using the mouse, each student’s wrist extension was recorded. Data consistent with summary values given in the paper “Comparative Study of Two Computer Mouse Designs” (Cornell Human Factors Laboratory Technical Report RP7992) are given here. 27 28 24 26 27 25 25 24 24 22 25 24 28 27 26 31 25 28 25 28 27 25 a. Use these data to estimate the mean wrist extension for people using this new mouse design using a 90% confidence interval.b. What assumptions are required in order for it to be appropriate to generalize your estimate to the population of Cornell students? To the population of all university students?c. Based on your interval from Part (a), do you think there is reason to believe that the mean wrist extension for people using the new mousedesign is…arrow_forwardDoes posting calorie content for menu items affectpeople’s choices in fast-food restaurants? According to results obtained by Elbel, Gyamfi, and Kersh(2011), the answer is no. The researchers monitoredthe calorie content of food purchases for children andadolescents in four large fast-food chains before andafter mandatory labeling began in New York City. Although most of the adolescents reported noticing thecalorie labels, apparently the labels had no effect ontheir choices. Data similar to the results obtained showan average of M = 786 calories per meal with s =85 for n =100 children and adolescents before thelabeling, compared to an average of M = 772 calorieswith s = 91 for a similar sample of n = 100 after themandatory posting.a. Use a two-tailed test with a = .05 to determinewhether the mean number of calories after theposting is significantly different than before caloriecontent was posted.b. Calculate r2to measure effect size for the mean difference.arrow_forward
- Weinstein, McDermott, and Roediger (2010) report that students who were given questions to be answered while studying new material had better scores when tested on the material compared to students who were simply given an opportunity to reread the material. In a similar study, an instructor in a large psychology class gave one group of students questions to be answered while studying for the final exam. The overall average for the exam was μ = 73.4, but the n = 16 students who answered questions had a mean of M = 78.3 with a standard deviation of s = 8.4. For this study, did answering questions while studying produce significantly higher exam scores? Use a one-tailed test with α = .01 and the Distributions tool to help. (Round your answers to three decimal places, when needed.) sMM = t-critical = t = The results indicate: Failure to reject the null hypothesis; answering questions while studying did not produce significantly higher exam scores…arrow_forwardWeinstein, McDermott, and Roediger (2010) report that students who were given questions to be answered while studying new material had better scores when tested on the material compared to students who were simply given an opportunity to reread the material.

- The article “Developing a Tool to Measure the Factors Influencing Nurses' Enjoyment of Nursing” (L. Wilkes, M. Doull, et al., Journal of Clinical Nursing, 2016:1854–1860) reports that in a sample of 124 nurses, 54 said that a busy workload had a positive effect on their enjoyment of their job. Can you conclude that less than 45% of nurses feel that a busy workload has a positive effect on their enjoyment of their job?arrow_forwardTo examine adolescent substance abuse, Li, Pentz, and Chou (2002) surveyed 1,807 middle school students from 57 schools. The results showed that a greater risk of adolescent substance abuse was associated with increasing numbers of parents and friends who were sub- stance abusers. However, friends’ use did not affect adolescent substance abuse when parents were nonusers. Is this an example of a survey research design?arrow_forward. Although there is a popular belief that herbal remedies such as Ginkgo biloba and Ginseng may improve learning and memory in healthy adults, these effects are usually not supported by wellcontrolled research (Persson, Bringlov, Nilsson, and Nyberg, 2004). In a typical study, a researcher obtains a sample of n = 16 participants and has each person take the herbal supplements every day for 90 days. At the end of the 90 days, each person takes a standardized memory test. For the general population, scores from the test form a normal distribution with a mean of μ = 50 and a standard deviation of σ = 12. The sample of research participants had an average of M = 54. Assuming a two-tailed test, state the null hypothesis in a sentence that includes the two variables being examined. Using the standard 4-step procedure, conduct a two-tailed hypothesis test with α = .05 to evaluate the effect of the supplements.arrow_forward
