y = 12 + .8643(150)
Solve for y.
A psychologist conducts a survey about the number of days per year a person was happy compared to the number of rainy days that occurred in their city. Let y be the number of days per year the person felt happy, and let x be the number of rainy days that occurred in their city. The regression equation from the study is y=12+0.8643x.
If there were 150 rainy days in a city, how many days would a person be predicted to feel happy?
