   Question

   The following regression equation for predicting $y =$ stress level is given:

   $\hat{y} =$ 200 - (Minutes Massage per Day) - 2(Minutes Exercise per Day) + 22(Gender) - 0.5(Gender*Minutes Massage per Day)

   Where the Gender variable is coded as Male = 0 and Female = 1.

   What is the predicted stress level score for a female who gets massages 30 minutes a day and exercises one hour per day?

   
   
   1. FALSE: 175
   2. FALSE: 72
   3. TRUE: 57
   4. FALSE: 35
   
   

   Solution

   The predicted score equals: $\hat{y} = 200 - 30 - 2 \times 60 + 22\times 1 - 0.5 \times 1 \times 30 = 57$
