Using the Standard Normal Table provided, find the following, (In case you forget what a zα is, it means that P(Z > zα) = α. zα is actually (1 − α)100th percentile of Z.) (a) (4) z0.40 = (b) (4) z0.60 = (c) (12) For a Normal random variable X ∼ N(µ = 5, σ = 10), find the 40th percentile of X, which is x0.60.
