Solution:
Let's sort the data from Smallest to Largest number
24,56,66,82,84,86,86,88,88,88,92,92,94,96,96,110
Quartile 1 = (16+1)/4 = 4.25 or 4th value i.e. 82
Quartile 3 = 3*(16+1)/4 = 12.75 or 13th value i.e. 94
So interquartile range = (94-82) = 12
So Lower boundary = (82-12*1.5) = 82-18 = 64
Upper boundary = (94+12*1.5) = 94+18 = 112
So outliers are 24,56
So it's answer is E. I.e. both 24 and 56 are outliers.

be any outliers (i.e., the value for which a score must be less
than to be consider an outlier and the value for which a number
must greater than to be considered an outlier.

1. On the following page are the exam scores on the first Statistics test for all my classes. Using everything we covered in the first three chapters of our textbook, describe the data. I recommend going through your notes and textbook, chapter by chapter. Include as much as you can – type of data, frequency distribution, histogram, numerical methods, etc. The standard deviation for the data is 16.7.

Student stress at final exam time comes partly from the
uncertainty of grades and the consequences of those grades. Can
knowledge of a midterm grade be used to predict a final exam grade?
A random sample of 200 BCOM students from recent years was taken
and their percentage grades on assignments, midterm exam, and final
exam were recorded. Let’s examine the ability of midterm and
assignment grades to predict final exam grades.
