True/False

SCENARIO 18-8
The superintendent of a school district wanted to predict the percentage of students passing a sixth- grade proficiency test.She obtained the data on percentage of students passing the proficiency test (% Passing),daily mean of the percentage of students attending class (% Attendance),mean teacher salary in dollars (Salaries),and instructional spending per pupil in dollars (Spending)of 47 schools in the state.
Following is the multiple regression output with Y = % Passing as the dependent variable, X₁ =% Attendance, X ₂ = Salaries and X₃ = Spending:

-Referring to Scenario 18-8,you can conclude that average teacher salary individually has no impact on the mean percentage of students passing the proficiency test,considering the effect of all the other independent variables,at a 10% level of significance based solely on the 95% confidence interval estimate for $\beta$ ₂ .
