Question

The relationship between number of beers consumed (x) and blood alcohol content (y) was studied in 16 male college students by using least square:s regression. The following regression equation was obtained from this study: y-hat=-0.01270+.0180x The above equation implies that: 

each beer consumed increases blood alcohol by.0127 

on average it takes 1.8 beers to increase blood alcohol content by .01 

After consuming 1 beer, blood alcohol equals .0180. 

each beer consumed increases blood alcohol by 0.018

Answer 1

\(\hat{y}=-0.0127+0.0180 x\)

Slope \(=0.0180\)

each beer consumed increases blood alcohol by \(0.018\)

Answer 2

Option D is Correct

Each bear Consumed Increases Blood Alcohol by 0.018

Because Coefficient of x is 0.0180 which is positive
