Assume a univariate quantitative data set, which contains fifty observations, has been organized by a grouped FDT with five classes. Let (cf)1 9, (rf)2 = 0.04, and fa 1. If, after adding twenty more observations (of same nature in the data set) to the data set, relative frequency of the fourth class is increased by 10%, then approximately what percentage of those added observations are in the fourth class? %3D a. 16%
