Dro 9. ed below are the amounts (dollars) it costs for marriage proposal packages at different baseball stadiums. Find the range, variance, and standard deviation for the agiven sample data, Include appropriate units in the results. Are there any outliers, and are they likely to have much of an effect on the measures of variation? 37 50 50 65 65 85 95 170 185 220 260 350 500 1750 2500 The range of the sample data is (1)- (Type an integer or a decimal. Do not round.) The standard deviation of the sample data is (Round to one decímal place as needed.) (2) – The variance of the sample data is (3) (Round to one decimal place as needed.) Are there any outliers and, if so, are they likely to have much of an effect on the measures of variation? O A. Yes, the smallest amounts are much lower than the rest of the data, and appear to be outliers. It is not likely that these are having a large effect on the measures of variation. O B. No, there are not any outliers. O C. Yes, the largest amounts…
