Question

24. Human body temperatures have a mean of 98.2° and a

standard deviation of 0.62º. Sally's temperature has a z-score
of z= 2.1. What is her temperature? Show work.

Answer 1

Explanation:

We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.

To find Sally's temperature we will use z-score formula.

, where = Mean, = Standard deviation.

Let us substitute our given values in z-score formula.

Multiply 0.62 to both sides of equation.

Add 98.20 to both sides of equation.

Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.
