question 75

Multiple Choice

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 10% 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.
