IQ scores are sometimes modeled as a continuous variable. Let X be the IQ score of a student, to be randomly selected at a University. Suppose that X has the normal distribution with a mean of 110 and a standard deviation of 8.

a.) Find the probability that a randomly selected student has an IQ higher than the national average of 100, but lower than 126.

b.) What IQ score has a probability of 0.01 of a randomly selected student scoring higher than it?
