Mr. Fisher suspects that right-handed people have faster reaction time than left handed people. He gave an online reflex test to separate random samples of 320 right-handed people and 360 left-handed people. Here are parallel box plots and numeric summaries of the data on reaction times (in ms) for the two groups. 200 250 Summary Statistics Group Name 1: Right Handed People 2: Left Handed People 300 350 Reaction Times (ms) 400 150 mean SD min Q₁ med Q3 max 246.719 59.36 170 195 240 285 430 271.111 70.782 180 222.5 260 307.5 500 Right Handed People Left Handed People 500 a) Write a few sentences comparing the distribution of reaction time for the two types of students. b) The distributions of the reaction times for both right handed people and left handed people is approximately normal. What is the probability that the mean reaction time of 10 randomly selected right-handed people from the 320 is at-least 28ms faster than the mean reaction time of 12 randomly selected left-handed people from the 360? (You need to show all 9 steps similar to the problem 9-11 on the Review of Chapter 7)
