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 = 100; σ = 12
P(x ≥ 120)
Solutions
Expert Solution
x has a normal distribution with mean : 
=100 and standard deviation: 
=12
Z-score for 120 = (120-100)/12 =20/12=1.67
From standard normal tables, P(Z<1.67) = 0.9525
P(x<120) = 0.9525
