Question

If Z has a standard normal probability distribution, find P(−2.71 < Z < −2.26).

Answer 1

Given that f Z has a standard normal probability distribution, you need to find:

$P(-2.71Since you need to find the area under the curve between those values, you can set up that:

[tex]P(-2.71Using the Standard Normal Distribution Table, you get:[tex]P(Z<-2.71)\approx0.034$$P(Z<-2.26)\approx0.0119$

Therefore:

[tex]P(-2.71Hence, the answer is:

[tex]P(-2.71
