Question:
A researcher carries out a QLR test using \(25 \%\) trimming, and there are \(q=5\) restrictions. Answer the following questions, using the values in Table 15.5 and the \(F_{m, \infty}\) critical values in Appendix Table 4.
a. The QLR \(F\)-statistic is 4.2. Should the researcher reject the null hypothesis at the \(5 \%\) level?
b. The QLR F-statistic is 2.1. Should the researcher reject the null hypothesis at the \(5 \%\) level?
c. The QLR F-statistic is 3.5. Should the researcher reject the null hypothesis at the \(5 \%\) level?
