### A NP researcher randomly sampled 100 women aged 50-65 years and measured their minutes of exercise in the past week, BMI, and depression.

1. Write the research and null hypotheses regarding the relationship between exercise and depression. Null hypothesis (H0) p = 0: Exercise in the past week doesn’t affect the depression score of the women aged 50-65.The alternative hypothesis (H1) p ≠ 0 : Exercise in past week affect the depression score of the women aged 50-65.2. Based on the test statistics in table 1, what is your conclusion regarding your research hypothesis? (Hint: discuss both the magnitude and direction of the relationship).The coefficient of correlation among minutes of exercise and depression score was -0.30(r). The coefficient of determination among minutes of exercise and depression score in women50-65 was -0.30 x -0.30 = 0.09 (9%) View Less >>
Part I (25%)A NP researcher randomly sampled 100 women aged 50-65 years and measured their minutes of exercise in the past week, BMI, and depression. Depression was measured using a Likert type scale consisting of 20 items. The summation score ranged from 20 to 100 and the higher the score, the higher the level of depression. The Pearson correlation coefficients (r’s) are summarized in the following table. For the analyses, a statistical significance level was set atα=0.05. Get solution
