Question

Question 13 [4 points]: What is the effect upon intelligence of listening to Fox News? Researchers order a crate of forty-two (of course) lab rats from Rodents-R-Us. (They wanted to use lab babies, but the ACLU threw a hissy fit.) Half (randomly selected) are exposed to Fox News, sixteen hours a day for a month. (The other eight hours they are allowed to engage in Priority #1-sleep.) The other half of the rats are exposed to a placebo program, on the same time schedule. At the end of the month, the rats are taught to run a maze. The researchers measure rat intelligence by noting how long it takes the rat to learn the maze. What procedure should they use to analyze the data? one sample test on means paired data test on means independent samples test on means test on a correlation one sample test on proportions paired data test on proportions independent samples test on proportions chi-square test
