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(g) of ears of corn
658 441.2 415.6
676.6 647.5 753
Checksum: 7356.7
586.6 610.7
478 652.5
428.6
487.9
520.5
Click Download CSV to download csv file of data. After downloading the file, you may want to save it as
an Excel Workbook (that is, .xlsx file type).
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.
Report your answer with all the decimal places.
Find the following:
a. The 36th percentile of these mass data 498. X
b. IQR 174. X
c. Apply the 1.5 IQR rule to search for outliers. Report the lower and upper cutoffs.
Lower: 216.: X Upper: 914.: X
d. Are there any outliers by the 1.5 IQR…

Which graph is more useful? Why?
O A. The graph in part a gives a worse picture of the true nature of the rate of change. The graph in part b makes it easier to see the changes in the early years.
O B. The graph in part a gives a…
