Given:

Z be a standard normal random variable, i.e,   .
a)



Use the excel formula, “=NORM.S.DIST(-1.72,TRUE)” to determine the p-value.


P(Z < - 1.72) = 0.0427



b)

P(Z > 3.5) = 1 - P(Z < 3.5)



Use the excel formula, “=NORM.S.DIST(3.5,TRUE)” to determine the p-value.


P(Z > 3.5) = 1 - 0.9998

P(Z > 3.5) = 0.0002
