Question details

Assume a normal distribution and find the following probabilities.

(Round the values of z to 2 decimal places. Round your answers to 4 decimal places.)

(a) P(x < 23 | μ = 27 and σ = 4)


(b) P(x ≥ 50 | μ = 30 and σ = 8)


(c) P(x > 27 | μ = 30 and σ = 6)

(d) P(21 < x < 26 | μ = 25 and σ = 4)


(e) P(x ≥ 84 | μ = 70 and σ = 1.80)
