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: Massig) of ears of corn 636.1 509.9 500.7 735.7 575.5 463.8 477.7 643.2 493.2 642.8 773.1 659.9 502.5 Checksum: 7614.1 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) IQR b) 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")
