Respuesta :
a) The predicted college GPA be for a student whose current high school GPA 3.2 is 2.97
b) The prediction error would be very high.
c) The point is intercept.
d) The predicted score of Y based on a known value of X should be represented as Y'
Given,
Slope = 0.704
Intercept = 0.719
(a) For aa =0.719, bb =0.704, and XX =3.2,
the predicted college GPA is,
Y′ = 0.719+(0.704⋅3.2)
= 2.9718
(b) For there is no correlation, the assumed two variables are considered to be independent, so predicting through linear equation them would not be justifiable if they are not linearly related. So the prediction error would be very high.
(c) The point is "intercept" where the estimated regression line is observed meeting the y-axis.
(d) As the alternate hypothesis is set up, rejecting any possible linear relationship, hence it is symbolized through "≠≠", hence it is non-directional.
(e) From part (a), we represented the predicted score though Y′Y′.
