How would i go about answereing this question?
The mean temperature in new york one summer was 86 degrees. if the temperature on july 22 of that summer was 82.1 degrees, what was the deviation from the mean that day?

You would go about it by subtracting mean temperature from the July 22 temperature. That is what "deviation" means. In this cse, you will get a negative number because the temperature was below the summer average on that day.

so would i do this:
82.1  86 = 3.9
now that i have the 3.9 would that be the final answer to the question "what is the deviation from the mean that day?" 
Yes, in degrees Fahrenheit
