You are investigating the mass of a sample of ears of corn. You gather the following data: Massig} of ears of corn ---EMIEI ---------IEIEI Chen: ksum: 404. i 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. Find the following: a} Ids b] sample standard deviation c]: Apply the 1.5 IQR rule to search for outliers. Report the lower and upper cuttoffs. Lower: Upper: Are there any outliers by the 1.5 IQR rule? (Enter "yes" or "no"; d] Apply the l-standard deviation rule to search for outliers. Report the lower and upper outtoffs. Lower: Upper: Are there any outliers by the 1-standard deviation rule? {Enter "yes" or "no"]: The lengths (in kilometers) of a random sample of 18 rivers on the South Island of New Zealand that flow to the Tasman Sea are listed in table below.
