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 = 18; σ = 3.4
P(x ≥ 30) =
Answer
using normalcdf
setting
lower = 30
upper = 99
mean = 18
and
sigma = 3.4
we get
P(X>30) = normalcdf(30,99,18,3.4)
= 0.0002
