We have a normal probability distribution for variable x with μ
= 24.8 and σ = 3.7. For each of the following, make a pencil sketch
of the distribution & your finding. Using 5 decimals, find:
(a)[1] PDF(x = 30); [use NORM.DIST(•,•,•,0)]
(b)[1] P(x ≤ 27); [use NORM.DIST(•,•,•,1)]
(c)[1] P(x ≥ 21); [elaborate, then use
NORM.DIST(•,•,•,1)]
(d)[2] P(22 ≤ x ≤ 26); [elaborate, then use
NORM.DIST(•,•,•,1)]
(e)[3] P(20 ≤ x ≤ 28); [z‐scores, then use
NORM.S.DIST(•,1)]
(f)[1] x* so that...
