Question (2 points) A Professor in the Department of Kinesiology wonders whether there is any difference in reaction times between right handed and left handed people. She takes a random sample of 42 right handed people and 20 left handed people and administers them the well validated "Wack-a-mole" reaction test. Average time for completing the test by the right handed sample is 90 seconds with a standard deviation of 10 seconds, and for the left handed sample 98 seconds with a standard deviation of 20 seconds. Test the professor's hypothesis at the .05 significance level. First, what are the null and alternative hypotheses? O HO: MRH = MLH; H1: MRH * HLH O HO: MRH > MLH; H1: MRH = MLH O HO: MRH = MLH; H1: MRH > MLH O HO: MRH * MLH; H1: MRH = MLH Question (6 points) Calculate the test statistic (to 2 decimal places). Test statistic equals............Question . (2 points) What is the critical value? A/ Question '_ (2 points) Make a decision. Do you reject or accept the null hypothesis? 0 Accept the null hypothesis and state there is no difference between the groups 0 Accept the null hypothesis and claim there is a difference between the groups 0 Accept the Alternative hypothesis and claim there is a difference between the groups 0 Accept the Alternative hypotheis and claim there is no a difference between the groups
