Question

02:12:29 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 49.716704 Intercept Hours Unsupervised Hours Playing Video Games Standard Error 7.299322 1.451838 9.717833 -Stat p-value 6.811140 0.000251 6.693467 0.000279 -0.846836 0.425088 1.091422 1.288823 Prev Copy Data Step 2 of 2: Indicate if any of the independent variables could be eliminated at the 0.05 level of significance.

Answer 1

Here,According to the value of p value we decide whether our hypothesis is eliminated or not eliminated. If p-value less than 0.05 (typically ≤ 0.05) is statistically significant. ... A p-value higher than 0.05 (> 0.05) is not statistically significant and indicates strong evidence for the null hypothesis. This means we retain the null hypothesis and reject the alternative hypothesis.

Here we clearly see that hours playing game has P value 0.42 only this value is not significant value and it being accepted because it is greater than P value at 0.05 confidence level. And Both the value such as Intercept as well as Hours Unsupervised is lesser than the P value. Obviously it being not accepted.

Thanks
