A psychologist would like to determine whether there is a relationship between depression and aging. It is known that the general population averages μ = 40 on a standardized depression test. The psychologist obtains a sample of n = 9 individuals who are all more than 70 years old. The depression scores for this sample are as follows: 37, 50, 43, 41, 39, 45, 49, 44, 48. a. On the basis of this sample, is depression for elderly people significantly different from depression in the general population? Test with α = .05 b. Compute estimated d and r2 c. Use the data to make a 90% confidence interval estimate of the level of depression in the elderly. d. Write a summary that demonstrates the how the outcome of the hypothesis test and estimated d would appear in a research report.

A researcher placed an advert in a university psychology department asking for third-year students to participate in a sleep experiment. Each student had a sleep tracker watch to wear at home for the two-week study. Each morning, they were asked to open the sleep tracker app to view their sleep quality data on their mobile phones. The students were unaware that the sleep data they could see on their phones had been manipulated by the researcher. Over the two weeks of the study, each student saw that he or she had poor sleep quality for seven random nights of the experiment and good sleep quality for the remaining nights. Every morning, after viewing the sleep data, each student completed a questionnaire about the previous night's sleep. One of the questions asked the students to rate how well-rested they felt, on a scale from 1-10, after the previous night's sleep. Apart from this, students were asked to continue their normal everyday activities. Which of the following best describes the experimental method used in this study? A. Field experiment B. Laboratory experiment C. Natural experiment D. Quasi-experiment

A clinical social worker is interested in evaluating three methods of treating depression: medication, cognitive restructuring, and exercise. A fourth treatment condition, a waiting-only treatment group, is included to provide a baseline control group. Sixty depressed students are recruited from the undergraduate student body at a large state university, and 15 are assigned to each treatment method. Treatments are administered for six months, after which each student is given a questionnaire designed to measure the degree of depression. The questionnaire is scaled from 0 to 100, with higher scores indicating a higher degree of depression. The mean depression values are then computed for the four treatments and compared to determine the relative effectiveness of each treatment. a. IV: The methods of treating depression. b. DV: The degree of depression. c. Sample: 60 students. d. Population: Degrees of depression among the college students in the university. e. Data: f. Statistic:
