Answer:

Step-by-step 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.
Answer:
