A personal trainer has been asked by the principal of a high school to examine the potential relationship between students’ physical activity (in number of minutes per week) and the number of televisions in the home. The data analysis result shows r = -.37, p = .07, using a two-tailed test, with an α level of .05.

  1. Formulate the null hypothesis and the alternative hypothesis in words and in notation. (1 point total: .5 for each hypothesis- both written and notation need to be correct for the .5 point)

  1. What is the conclusion of the hypothesis test (use wording of “reject” or “fail to reject”)? Explain how you made the decision about the test result. (1 point total: .5 for conclusion, .5 for rationale)

  1. What is the effect size of this test? (1 point)

A clinic specializing in eating disorders would like to evaluate the effectiveness of a nutritional training program on binge eating disorder (BED). A psychologist was hired to conduct a small study to examine the potential effect of nutritional training on number of binges per month. The psychologist recruited 10 patients in the clinic to participate in a nutritional training program and 12 patients in the clinic with similar demographics who do not participate in the nutritional program. Afterward, all participants...

In a cognitive psychology experiment, the researcher is interested in whether encoding condition has an effect on memory for a list of words. She recruits 16 subjects to participate in the experiment. Each subject comes to the lab twice to be tested in two different encoding conditions and their memory performance scores are listed below. The researcher would like to leave the hypothesis non-directional without predicting which encoding condition would lead to better memory, and she sets the significance level...

A school counselor in a high school would like to try out a new conflict-resolution program to reduce aggressiveness in students. She first surveyed 16 students using a 20-item instrument to measure their levels of aggression (on a scale of 0 to 10, with higher numbers meaning higher aggression levels). One month after the conflict resolution program was implemented, the students were given the same survey. The data are listed in the table below. The school counselor/researcher has set the...

Independent-Samples t-Test In a research project, researchers track the health and cognitive functions of the elderly in the community. To examine any possible gender differences in their sample, they want to see if the females and the males differ significantly on the education level (number of years of formal schooling). The researchers are not predicting any direction in the possible gender differences so the hypotheses should be non-directional. They would like to run a two-tailed test with α = .10....

For my PSY 240 course, I implemented a new practice of bringing in guest speakers at various stages of life. The goal is to have students observe real-life examples of developmental stages and thus have higher final course percentage scores as a result. In order to see if this new element was helpful to students, I compared results from the final percentage scores of my current class to the existing pool of past final percentage scores from all my previous...

1. Large Sample Proportion Problem. A survey was conducted on high school marijuana use. Of the 2266 high school students surveyed, 970 admitted to smoking marijuana at least once.  A study done 10 years earlier estimated that 45% of the students had tried marijuana. We want to conduct a hypothesis test to see if the true proportion of high school students who tried marijuana is now less than 45%.   Use alpha = .01. What is the conclusion for this test? A)Based...

A geriatric research project has been tracking the health and cognitive functions of the elderly population in Arizona. The table below shows the memory test scores from 16 elderly residents, tested first when they were 65 years old and again when they were 75 years old. The researcher wants to know if there is a significant decline in memory functions based on this sample. The alpha level was set at α = .05 for the hypothesis test. Memory score Subject...

A cohort study is conducted to assess the effectiveness of a 4-week weight-loss intervention program among overweight men. Sixty participants were randomized into two groups. Group 1 worked with a personal trainer to come up with a physical activity regimen that would best fit their lifestyle, while Group 2 worked with a dietician to co-design a diet program to which the men would most likely adhere. Mean BMI was assessed for each group at the end of the 4 weeks....

Problem I. An experiment was done with 30 participants to test the effect of the type of attachment style that one has (i.e., secure, anxious, or avoidant) on how long one (in years) is married to her/his spouse. Higher scores below indicate a greater number of years. Use an alpha level of .05 (p = .05).                Secure                  Anxious               Avoidant                M1 = 10                M2 = 9                  M3= 5                   k =                               n1 = 10                  n2 =...
