Quizplus · Accepted Answer

The question states that the null hypothesis should be rejected at a 5% level of significance when testing whether there is a significant relationship between the percentage of students passing the proficiency test and the entire set of explanatory variables. This indicates that the multiple regression output showed a statistically significant relationship between the dependent variable and the independent variables, so the null hypothesis should be rejected in favor of the alternative hypothesis. The output does not provide the result of a hypothesis test for the significance of the relationship between the dependent variable and the set of explanatory variables. Therefore, the statement cannot be based on the given information.
