You are interested in understanding why some people send more e-mail messages than others do. One possible explanation may be the age of the individual. Older people tend to be less computer savvy, and may have fewer friends who use e-mail.
 
  You examine the number of e-mails a person sends weekly using regression analysis and come up with the following equation of the regression line:Number of e-mails = 63 - 0.5 Age. Interpret these results.

Answer to Question 1

There appears to be a negative relationship between the age of a person and the number of messages they send.
The Y intercept b0 = 63 is meaningless in this situation.
The slope b1 = -0.5. This means that for each year older a person is, we would expect them to send approximately 0.5 fewer e-mails per week.

Answer to Question 2

D
