Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.) μ = 14.6; σ = 3.8

0.0003

Step-by-step explanation:

for the indicated probability

we need to find : Probability (P) (X > or = 30) = 1 - P (X < 30)

z-score (30) = (30 - 14.6) / 3.8 = 4.053

looking in z-tables for the corresponding probability

P (x<30) = 0.99997

indicated probability

P (X > or = 30) = 1 - 0.99997 = 0.0003 (answer)
