Answer:
A ; D ; B ; D
Step-by-step explanation:
Given the data:
Dependent Independent
Variable Variable
Y ___ X
5 __ 15
7 __ 12
9 __ 10
11 __ 7
The general regression equation is of the form /
Y = B0 + BiX
Y = dependent variable ; B0 = intercept ` B1 = slope ; X = independent variable
Using calculator, the model obtained for the model is :
Y = 16.41176 - 0.7647x
Hence,
Least square estimate for b1 = - 0.7647
Least square estimate for b0 = 16.41176
Correlation Coefficient (R) = - 0.99705
The Coefficient of determination (R²) = - 0.99705^2 = 0.994108
.
