Human body temperatures are normally distributed with a mean of 98.20 and a standard deviation of 0.62.
Find the z-score corresponding to a body temperature of 97.93.
This is what I did.
97.93 - 98.20 / .62
I got -.44.

WOuld a temperature of 99.71 be considered unusual?
99.71 - 98.20 / .62.
My answer 2.44. Yes because it's more than 2 SD.
