Normal percentile chapter 5 homework

### Question Description

I need support with this Statistics question so I can learn better.

The average beginning annual salary for teachers in California is \$41,181. Assume that this is a normal distribution with a standard deviation of \$725. One quarter of starting teachers in California will make " at least"  much money per year?

Student has agreed that all tutoring, explanations, and answers provided by the tutor will be used to help in the learning process and in accordance with Studypool's honor code & terms of service.

mean =41181

sigma =725

z value for 25 percentile or first quartile is -0.67

Hence 41181-0.67*725=\$40695.25
