1. A researcher is investigating the effects of a new drug on the ability of rats to learn to navigate a maze. She is worried that differences in activity levels might influence the results, so she give them a baseline activity test and matches them to form eight pairs. One group is then given the drug and the other group a placebo. Here are the results in terms of number of trials it took each pair to navigate the maze without any errors. Pair Placebo Drug 1 4 2 4 2 3 5 4 7 4 5 3 2 6. 5 7 4 8 6. 3 (a) Formally state the null and alternative hypotheses and perform the hypothesis at the .05 level of significance.
