Consider the following samplo of five masurements. 4,2,2,0,5 o a. Caksuste the range, s2, and s tange = s2= (Round to one decimal ploce as needed.) (Round to two decimat places as needed.) b. Add 4 to each meaburemont and repeat part a. range = s2= (Round to one decimal place as needed.) (Round to two deomal places as needed) c. 5ubtract 3 from each measurement and repeat part a. range = a2= (Round to one decimal place as needed) (Fround to two decinal places as needed) A. The variebility is decreased by the amount actracted from each measurament. B. The variabilty is multylsd by the amount added bor suttracied from each masurement d. Considering your answers to parts a,b, and c, what seams to be the effect on the variability at a data set by adding the same number to or suberncting the same number trom each measurement? A. The variability is decreased by the amount subbacled from each measurement. B. The variabaty is multipled by the amount added to or suberacted from each measurement. C. There is no effect on the variability D. The variabaty is increased by the amount added to each measurement
