Question

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 = 15.3; σ = 4.3

P(10 ≤ x ≤ 26) =

Answer 1

This is a normal distribution question with

P(9.0 < x < 27.0)=?


This implies that


PS: you have to refer z score table to find the final probabilities.
