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 correlation coefficients (Pearson's rs) are summarized in the following table. For the analyses, statistical significant level was set at =0.05. Table 1: correlation among minutes of exercise, BMI and depression Exercise in past week (minutes) -0.20 -0.30 (P <0.05) BMI Depression score BMI 0.21 1. Write a research and null hypotheses regarding the relationship between exercise and depression. HO-Depression score has no effect on bmi. H1- As the depression score increases, so will bmi.
