Critical Thinking Consider the numbers2 3 4 5 5(a) Compute the mode, median, and mean.(b) If the numbers represent codes for the colors of T-shirts ordered from acatalog, which average(s) would make sense?(c) If the numbers represent one-way mileages for trails to different lakes,which average(s) would make sense?(d) Suppose the numbers represent survey responses from 1 to with1 = disagree strongly, 2= disagree, 3 agree, 4 agree strongly,and 5 = agree very strongly. Which averages make sense?14. Critical Thinking Consider two data sets.Set A: n = 5; x = 10Set B: n= 50; x = 10(a) Suppose the number 20 is included as an additional data value in Set A.Computex for the new data set. Hint: Ex= nx. To computex for the newdata set, add 20 to Ex of the original data set and divide by 6.Copyright 2019 Cengage Learning. All Rights Reserved.
