No idea where to begin with this z-score
Human body temperatures are normally distributed with a mean of 98.20 and a standard deviation of 0.62.
Find the body temperature corresponding to a z-score of z=1.73

I have no idea where to begin.

We know that $z=1.73, \mu=98.2, \sigma=0.62$. Plug those into the formula $z=\frac{x-\mu}{\sigma}$, you can solve for x. And that will be your answer .
