Normal Probability Distribution

For a standard normal random variable Z, (mean = 0, S.D.T. = 1)

1. Find probabilities for z, (left, right, between area using z table)
ex: P(z < 0.23) = , P(z >1.28) = , P(-0.25 < z < 1.5) =

2. Find a specific z-value given a probability (area)
Ex: given P(z < Z0) = 0.10, Z0 = ?
