A set of final exam scores in an organic chemistry course was found to be normally distributed, with a mean of 73 and a standard deviation of 8.

What is the probability of getting a score higher than 71 on this exam?

The probability is

P(X>71) = P((X-mean)/s >(71-73)/8)

=P(Z>-0.25)

=0.5987 (check standard normal table)
