A social psychologist studying mass communication randomly assigned 77 volunteers to one of two experimental groups. Fifty-seven were instructed to get their news for a month onlyfrom television, and 20 were instructed to get their news for a month only from the Internet. After the month was up, all participants were tested on their knowledge of several politicalissues. The researcher simply predicted that there is some kind of difference. These were the results of the study. TV group: Mty = 22, S, = 2; Internet group: M, = 26.2, s = 3. The pooledvariance, rounded to four decimal places, is 2.2533. Complete parts (a) and (b) below.(a) Figure the estimated effect size for this study. Let the TV group be sample 1 and let the Internet group be sample 2.The estimated effect size for this study is

After a product recall, a company solicits feedback from a random sample of 100 customers regarding their opinion about the company since the recall. Customers were asked, "Do you approve, disapprove, or have no opinion about the company?” The public relations department is concerned that the opinions may be equally distributed across these three options. The survey reveals that 38 customers approve, 45 disapprove, and 17 have no opinion. They decide to carry out a test of the following hypotheses: H0: Customer opinion is equally distributed across the three options. Ha: Customer opinion is not equally distributed across the three options. The chi-square test statistic is χ2 = 7.77 and the P-value is between 0.02 and 0.025. What conclusion should the public relations department make? Use α =0.05. Reject H0. There is convincing evidence that the distribution of customer opinion is equally distributed across the three options. Reject H0. There is convincing evidence that the…

1. State whether it will experimental or observational 2. If observational, identify which type specifically (retrospective cohort, prospective cohort, case-control, cross-sectional, ecological) 3. Briefly explain how you can tell what type of study it is. We select a group of 1,000 middle-aged volunteers without kidney disease who are likely to suffer from insomnia/anxiety. We assign them randomly into two groups. Group 1 is told to live their lives as normal and take any meds proscribed by their doctor. Group 2 is told not to use BZDs for 2 years, and doctors prescribe Group 2 with natural alternatives to BZDs. After those 2 years, we follow them up and check to see who developed kidney disease in each group and compare the groups.
A tutor who teaches four tutorials is interested in exploring whether certain colours are better than others for student learning. To test this, she designed an experiment to see whether different colour PowerPoint slides impact students’ final exam grades. Each of the tutor’s four tutorials were presented with a different colour background in the PowerPoint slides throughout the semester (red, blue, yellow or green). The average final exam grade for each class was measured. What test would the tutor use to determine whether there were any differences in final exam grades between the classes? One-way independent groups ANOVA Repeated measures ANOVA Pearson's correlation Independent groups t-test
When I was an undergraduate, I helped my father conduct some Child Psychology research about parental influence on gender bias. In this study we interviewed 158 kindergarteners. Our initial question was "What is your favorite color?" where we studied the distribution of "Pink" and "Blue" responses. To our surprise, 38 of the students interviewed responded "Turquoise". Use this information to select the response which correctly answers the question. According to this description, which term best describes our study? O Cross-Sectional O Retrospective O Prospective

A researcher is interested in factors related to academic performance of students. She hypothesized that for undergraduate students, there is an association between academic majors (STEM, Business, Education, Nursing) and amount of time spent studying each week (less than 3 days, 3 to 6 days, everyday). To test her hypothesis, she randomly selected 1000 undergraduate students from various colleges/universities in Texas, and then classified each participant according to their major and amount of study time each week. For her study, she found test-statistic of 23.75 and a p-value of 0.0006. Using this information, fill in the necessary information below for her test. Distribution used: a. chi-square distribution, 3 degrees of freedom b. chi-square distribution, 4 degrees of freedom c. chi-square distribution, 6 degrees of freedom d. chi-square distribution, 12 degrees of freedom
