2 (f) If a new grade, Y, is added to the data set, so the data set becomes 12, 78, 24, 28, 42, 60, 94, 62, 68, Y (where Y is the new grade), what is the maximum amount by which the new median could differ from the old median (in 2(a))? (This means, if the new median is mnew and the old median that you found in 2(a) was mold, what is the maximum value that |mnew−mold|can have? Here,...
