2. You conduct a linear regression in which the number of hours per week spent exercising is used
to predict the respondent's overall general health, measured on a scale from 0 to 100 with 100
being the best possible health. You obtain the following results: b = 4,5; a = 37. Using the
general formula for a regression line, calculate the predicted values for overall general health for
respondents who spend 0 hours per week exercising,3 hours per week exercising, and 12 hours
per week exercising.
