A researcher examining factors that influence sleep quality tested the effects of two variables. Her first factor has 2 levels and the second factor has 3 levels. She recruited 30 participants. Use the following source table to answer the next few questions.
$\begin{array}{lcc}
\hline \text { Source } & S S & d f& MS &F \
\hline \text { Factor 1 } & 739.1 & 1 & 739.1 & 1.03 \
\text { Factor 2 } & 4526.8 & 2 & 2263.4 & 3.15 \
\text { Factor 1 }{ }^{*} \text { Factor 2 } & 2819.3 & 2 & 1409.65 & 1.97 \
\text { Error } & 17247.2 & 24 & 718.633 &\
\hline
\end{array}$ What is the critical value for each F ratio at the .05 significance level, and what is the observed F? Are any of the effect significant?
