23. Forest bathing, also called Shinrin-yoku, is the practice of taking short, leisurely walks in a forest to enhance positive health. To test if forest bathing and mood are related, a clinical psychologist records the time spent forest bathing in minutes (X) and the corresponding change in mood using a standard self-report affect grid (Y) among 8 patients with a history of depression. The data are given in the following table. Time Spent Forest Bathing (in minutes) Change in Mood X Y 32 +24 24 +20 28 +25 17 +22 12 +16 1. Compute the method of least squares to find the equation of the regression line. 2. Use the regression equation computed in part (a) to determine the predicted change in mood of a person who spends 20 minutes forest bathing
