Following is the multiple regression output with Y = % Passing as the dependent variable,X1 = Salaries and X2 = Spending: 
-True or False: Referring to Table 14-15,you can conclude definitively that instructional spending per pupil individually has no impact on the mean percentage of students passing the proficiency test,taking into account the effect of mean teacher salary,at a 10% level of significance based solely on but not actually computing the 90% confidence interval estimate for β2.
