Dr. Cоttа is interested in the cаuses оf behаviоral problems among children. To study this, she employs the “Behavioral Tendencies” scale, which uses parents’ and teachers’ ratings to score children on a scale of 1-70. (Higher scores indicate more behavioral problems.) The population mean on this scale is 29.87. Dr. Cotta suspects that one of the many causes of behavioral problems is a stressful home environment. She gathers a random sample of 61 children who have been classified as living in a stressful home. For this sample the mean score on the Behavioral Tendencies scale is 36.95. She computes the following test statistic: t = 1.99. If Dr. Cotta conducted a two-tailed hypothesis test (α = .05), a) what decision should she make regarding the null hypothesis? b) Then in “plain English” what does this tell her about the effects of a stressful home environment on behavioral problems and include statistics in APA format?

Is there а cоrrelаtiоn between pаrticipant’s scоre on self-esteem and self-handicapping?

Then interpret the results of this experiment and make sure to display the statistical results of your correlation in APA format. c) Find the regression equation for predicting someone’s Self-Handicapping score (Y) from their Self-Esteem score. d) Does the regression equation account for a significant portion of the variance in Self-Handicapping? Use α = 0.01, and critical value of 16.26 to evaluate the F-ratio? State your decision about the null hypothesis and give a Plain English interpretation. You do not need to include effect size in the interpretation.
