SCENARIO 14-15 The superintendent of a school district wanted to predict the percentage of students passing a sixthgrade proficiency test. She obtained the data on percentage of students passing the proficiency test (% Passing), mean teacher salary in thousands of dollars (Salaries), and instructional spending per pupil in thousands of dollars (Spending) of 47 schools in the state. Following is the multiple regression output with Y = % Passing as the dependent variable, X 1 = Salaries and X 2 = Spending: -Referring to Scenario 14-15,you can conclude that instructional spending per pupil has no impact on the mean percentage of students passing the proficiency test,considering the effect of mean teacher salary,at a 5% level of significance using the confidence interval estimate for $\beta$₂.

Quizplus · Accepted Answer

Since the confidence interval for the coefficient of Spending includes 0 and the p-value for it is greater than 0.05, we can conclude that instructional spending per pupil has no significant impact on the mean percentage of students passing the proficiency test, considering the effect of mean teacher salary, at a 5% level of significance. Therefore, the statement is true.
