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 = 113; σ = 19

*P*(*x* ≥ 90) =

Step 1

If a random variable *x* has a distribution with mean µ and standard deviation σ, then the z-score is defined as,

Step 2

**Finding the probability, P (x ≥ 90):**

It is given that µ = 113 and standard deviation, &sigma...
