Question

A variable XX follows a normal distribution with a mean of μ=85\mu = 85 and a standard deviation of σ=10\sigma = 10 . Interpret P(X40)P(X .

Accepted Answer

Highly improbable under this normal distribution.

Answer

Very likely to occur under this normal distribution.

Answer

Somewhat probable under this normal distribution.

Answer

Almost certain to occur under this normal distribution.

A variable XX follows a normal distribution with a mean of μ=85\(\mu\) = 85 and a standard deviation of σ=10\(\sigma\) = 10 . Interpret P(X<40)P(X < 40).
