# (Solved): Having just aced your college stats course, you suggest that they compare the Hybrid County average ...

Having just aced your college stats course, you suggest that they compare the Hybrid County average and the Remote County average with the average from a school in a rural part of the state that brought the children back to school full time in September of the previous year, due to the very low rate of infections in that area. Fifth graders in that school also take the same test at the same time, just before Easter. The principal of the Rural County school likes the idea. The statistician in Rural County says that the correct $$H_{0}$$ for this analysis is: $$\mu_{\text {Hybrid County }} \neq \mu_{\text {Remote County }} \neq \mu_{\text {Rural County }}$$ 7. Is this statement correct? Yes or No? (1 point) 8. Using ANOVA to compare the means of Remote $$(n=30)$$, Hybrid $$(n=40)$$, and Rural County $$(n=15)$$ fifth graders, what will be the $$d f$$ for this analysis that you will use to obtain the critical F from the F table? (1 point) a. $$d f_{\text {between }}=3, d f_{\text {within }}=84$$ b. $$d f_{\text {between }}=2, d f_{\text {within }}=84$$ c. $$d f_{\text {between }}=2, d f_{\text {total }}=84$$ d. $$d f_{\text {between }}=2, d f_{\text {within }}=82$$
