You work for a large farm with many fields of corn. You are investigating the mass of a sample of ears of corn. You gather the following data: Mass (in grams) of ears of corn 793.1 577.7 516.8 569.4 666 507.7 472.2 573.1 614.7 470.5 464.9 627.9 738 Some of the masses in the sample seem much larger than the rest. You decide to make several calculations describing the "spread" of the data set. You hope to use them to help in the search for outliers. You have already computed the following: Sample mean = 584, Standard deviation = 103 , Median = 573.1, 1st Quartile = 489.95, and 3rd Quartile = 646.95 . a) Apply the 1.5 IQR rule to search for outliers. Report the lower and upper cuttoffs: Lower: Upper: Enter an integer or decimal number [more..] Are there any outliers by the 1.5 IQR rule? (Enter "yes" or "no") b) Apply the 2-standard deviation rule to search for outliers. Report the lower and upper cuttoffs. Lower: Upper: Are there any outliers by the 2-standard deviation rule? (Enter "yes" or "no" Submit
