Question

Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Enter a number. Round your answer to four decimal places.) μ = 22; σ = 4.2 P(x ≥ 30) =

Answer #1

Solution :

Given that ,

mean = = 22

standard deviation = = 4.2

P(x 30) = 1 - P(x 30)

= 1 - P[(x - ) / (30 - 22) / 4.2]

= 1 - P(z 1.90)

**= 0.0287**
