1) Assume Z is a random variable with a standard normal distribution (that is, a mean of µ = 0 and a standard deviation of 1).
What is P(Z < -0.5)? How about P(Z > -0.5)? (Section 5.1)
2) Now let’s that assume X is a random variable that has a normal distribution with µ = 100 and a standard deviation of 15.
What is P(X > 115)?
