Question 6

Question 6 of 11 Step 1 of 2 01:32: 59 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 (x) is the number of hours unsupervised each night, and the second independent variable (x2) is the number of hours of video games each night. Standard Error Coefficients 65.014540 4.558966 Hours Playing Video Games-0.663974 t Stat 5.443593 11.943314 0.000021 1.030316 4.424825 0.004448 1.160644-0.572074 0.588048 p-value Intercept Hours Unsupervised Copy Data Next Step 1 of 2: Write the multiple regression equation for the computer output given. Round your answers to three decimal places. Answer(How to Enter) 1 Point Keypad Hide

Explanation / Answer

for writing multiple regression ,we have to write summation of beta coefficient *variable

hence y^ = 65.01454 + 4.558966 *x1 -0.663974* x2   

y^ = 65.015 + 4.559 *x1 -0.664 *x2 {after rounding off}

if p-value is more than level of significance (0.01 here)

the variable is insignificant and can be eliminated

here p-value of x2 is 0.588048 > 0.01

hence x2 can be eliminated

p-value of x1 = 0.004448 < 0.01 , hence x1 can't be eliminated .

option B) x2 is correct
