How to Use the Z-table to Compute Probabilities of Non-Standard Normal Distributions
Problem 758
Let $X\sim \mathcal{N}(\mu, \sigma)$ be a normal random variable with parameter $\mu=6$ and $\sigma^2=4$. Find the following probabilities using the Z-table below.
(a) Find $P(X \lt 7)$.
(b) Find $P(X \lt 3)$.
(c) Find $P(4.5 \lt X \lt 8.5)$.
