Question

Let z be a random variable with a standard normal distribution. Find the indicated probability. What is the probability that P(z ≤ 1.18)?

Answer 1

`P(Z<=1.18)=0.8810`

Explanation:

`" For "X~N(0,1)" we want "P(z<=1.18)`

The Normal distribution tables gives values for

`P(Z,<=z)`

so looking up the tables we find

`P(Z<=1.18)=0.8810`
