It is thought that there are a variety of factors that affect a teacher's salary. Using the following
Printout and sample data, determine whether the holding of a PhD degree is a signiﬁcant variable
When tested at the 1% level of signiﬁcance.
X1 is years of teaching experience, X2 is principal's rating and x3 is the presence of a PhD or not.
A) Since the p-value is less than the level of signiﬁcance, the null hypothesis is rejected, and so the holding of a PhD should be included in the analysis.
B) Since the p-value is less than the level of signiﬁcance, the null hypothesis is accepted, and so the PhD should not be included in the analysis.
C) Since the p-value is more than the level of signiﬁcance, the null hypothesis is accepted, and so the PhD should not be included in the analysis.
D) Since the p-value is more than the level of signiﬁcance, the null hypothesis is rejected, and so the PhD should be included in the analysis.
