Given that f Z has a standard normal probability distribution, you need to find:
[tex]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[/tex][tex]P(Z<-2.26)\approx0.0119[/tex]Therefore:
[tex]P(-2.71Hence, the answer is:[tex]P(-2.71
