Choose the comect answer below in distaros the acornv is estmated to change by the value of the soe Cick to select your answerExplanation / Answer
a.
the correct answer B: y=beta0+beta1x+eps.
since simple linear regression model is defined as above.where x is regress on y
b.
using simple linear regression appropriate fitted model is
ycap=43.33+0.02775*x
where beta0=43.33 is y-intercept
c.
the correct answer is B: since a drive with distance 0 is outside the sample data, y-intercept has no practical interpretation.
since if a distance is 0 then in the model there is only intercept value remain.and it has no interpretation.
d.
the correct answer is A: for each additional yard in distance, the accuracy is estimated to change by the value of the slop.
since the fitted model is ycap=43.33+0.02775*x mean each unit change in X, slop time change in accuracy.
e.
the slop parameter help to determine if the golfer"s concern is valid because the positive or negative sign of slop parameter determines whether the accuracy increase or decrease with distance.
if slop coefficient has positive(negative) sign then its accuracy will increase(decrease) with distance.
Y = 0.02775*X + 43.33Related Questions
