have a larger variance.
ii Let random variable X be the height of a random CS5002 student in feet and X' be the height of
a student from the same group in millimeters². The variance of X' is greater than the variance
of X.
iii For every positive a, b e R there exists an no such that:
n > no + an > bn²
2 Assume that not all students have the same height
