Variable z follows the standard normal distribution. For each of
the following, make a pencil sketch of the distribution & your
finding. Using 5 decimals, find:
(a)[2] P(z ≤ ‐2.9); [use NORM.S.DIST(•,1)]
(b)[2] P(z ≥ 2.4); [elaborate, then use
NORM.S.DIST(•,1)]
(c)[2] P(‐1.6 ≤ z ≤ 1.7); [elaborate, then use
NORM.S.DIST(•,1)]
(d)[2] z* so that P(z ≥ z*) = 0.07; [use NORM.S.INV(•)]
(e)[2] z** so that P(z ≤ z**) = 0.025. [use NORM.S.INV(•)]
