Which company should have more predictable costs? Choose the comect answer below O A Fresh has less variator. Because Fresh has less variation estmates of repar costs wil tend to be less accurat. Thus. Oool wa have more predctablecosts. B· Qool has less var alon. Because Qool has less variation, estimates ofrepar ests tend to be less accurate Thus. Fresh wa have more predictable costs. O C. Fresh has less variation. Because Fresh has less variation, essmabes of repair costs will tend to be more accurate, so the costs will tend to be more predictable O D. Gool has less variation Because Clool has less variation, estimales of repair costs will tend to be more accurate, so the costs will tend to be more predictable Cick to select your answer and then click Check Answer All parts showing Clear All Finail CheckExplanation / Answer
the whiskers (the lines of the boxplots) represent the range of the data in the boxplot. so the range is clearly high for the fresh air company (bottom boxplot) , as oppose to the first box plot whose range is less. this also means that the data points in the first boxplot are clousre to the mean in this case
as thier os less variation hence the estimates would be more accurate , hence the correct choice is D
