Question
Suppose that we know, in addition, that
the standard deviation of the student's test
score on the final is 9.7.
(b) What is a lower bound of the
probability (in three decimal places) that
the student will score between 57.9 and
77.9 ?

Suppose that the test score of a student
taking the final of a probability course is a
random variable with mean 67.9.
(a) Give an upper bound for the probability
(in three decimal places) that the student's
test score will exceed 95.
