All work must be shown:
Find the Z scores for the following normal distribution problems
a. µ = 604, σ = 56.8, X ≤ 635
b. µ = 48, σ = 12, X < 20
c. µ = 111, σ = 33.8, 100 ≤ X ≤ 150
d. µ = 264, σ = 10.9, 250 < X < 255
e. µ = 37, σ = 4.35, X > 35
f. µ = 156, σ = 11.4, X ≥ 170
Shade and label graphs if possible.
