Answer:a) i) Mean = 72ii) Median = 72iii) Mode = 72b)69, 70, 71, 72, 72, 72, 73, 74, 75Step-by-step explanation:a. To find mean, median and modeIt is given that all the 9 students get 72 marks.Therefore the data set be,72, 72, 72, 72, 72, 72, 72, 72 72i) mean = (sum of data)/(total number of data) = (9 * 72)/9 = 9ii) Median - Central data in the data set when arranging ascending or descending order72, 72, 72, 72, 72, 72, 72, 72 72Median = 72iii) Mode - Most repeating data in the data setHere mode = 72b). To find a data set69, 70, 71, 72, 72, 72, 73, 74, 75Here Mean, mode and median are all 72
