Karen Wilsonperson and half the time of a white person. The table below shows the means and standard deviations for reaction times (the time to decide if the picture is of a gun or a tool) after either a black or white prime. In Experiment 2, participants were told to decide as fast as possible.) Explain the results to a person who has never had a course in statistics. (Be sure to explain some specific numbers as well as the general principle of the mean and standard deviation.)PRIMEBlackWhiteTargetMSDMSDExperiment 1Gun4236444173Tool4545744660Experiment 2Gun 2992829531Tool3072930429??????????????????????????Chapter 3 Practice Problems 14, 15, 22, & 2514. On a standard measure of hearing ability, the mean is 300 and the standard deviation is 20. Givethe Z scores for persons who score (a) 340, (b) 310, and (c) 260. Give the raw scores for persons whose Z scores on this test are (d) 2.4, (e) 1.5, (f) 0, and (g) -4.5.Z=(SM – PM) / SD where SM is the sample mean, PM is the population mean, and SD is the population standard deviation.
