-True or False: Referring to Table 17-8,you can conclude that the mean teacher salary individually has no impact on the mean percentage of students passing the proficiency test,taking into account the effect of all the other independent variables,at a 1% level of significance based solely on the 95% confidence interval estimate for β₂.
