Question
Write the multiple regression equation for the computer output given. Round to three decimal places:
y^ = ..... + ..... x1 + .....x2
Indicate if any of the independent variables could be eliminated at the 0.01 level of significance
The following table was generated from the sample data of 10 junior high students regarding the average number of hours they are unsupervised per night, the average number of hours they play video games per night, and their final grades in their math class. The dependent variable is the final grade, the first independent variable () is the number of hours unsupervised each night, and the second independent variable (2) is the number of hours of video games each night. Coefficients Standard Error Stat p-value 97.171862 5.018598 19.362352 0.000001 Hours unsupervised |-5.119253| 1.217086 |-4.206154|0.005647 Hours Playing Video Games 1.636387 1.2783181.2801090.247769 InterceptExplanation / Answer
from above given output:
yhat =97.172+(-5.119)x1+1.636*x2
as p value for hours playing video gmaes(X2 variable) is greater than 0.01 level ; which means it is not significant and hence needs to be eliminated
