A recent study investigated whether the number of positive health behaviors (e.g., exercising, eating healthy) is predictive of a person's score on a happiness index, such that as positive health behaviors go up, happiness goes up. The results from the study, which was conducted with 12 people, were as follows: r = 0.63 and SSY = 56.0.

What is the MSregression?  What is the MSresidual?  What is the calculated test statistic?

Do you reject the null?

Given your conclusion about the null, in a sentence describes what the results of the study were.

Solutions

Expert Solution

Null Hypothesis, Ho: There is no relationship between positive health behavior and happiness scores of a person.

Alternative Hypothesis,Ha: There is significant relationship between positive health behavior and happiness scores of a person.

Conclusion: We have sufficient evidence at 5% level of significance to conclude that the number of positive health behaviors (e.g., exercising, eating healthy) is predictive of a person's score on a happiness index, such that as positive health behaviors go up, happiness goes up.

A health psychologist tests a new intervention to determine if it can change healthy behaviors among siblings. To conduct the this test using a matched-pairs design, the researcher gives one sibling an intervention, and the other sibling is given a control task without the intervention. The number of healthy behaviors observed in the siblings during a 5-minute observation were then recorded. Intervention Yes No 5 4 3 5 6 4 6 5 6 4 4 4 (a) Test whether or...
