Mathematics
calculating percentile score

Question Description

I’m studying for my Mathematics class and don’t understand how to answer this. Can you help me study?

Body temperatures of healthy adults are normally distributed with a mean of 96.20 degrees F and a standard deviation of 0.82 degrees F, what is the percentile score if your temperature is 97 degrees F

Student has agreed that all tutoring, explanations, and answers provided by the tutor will be used to help in the learning process and in accordance with Studypool's honor code & terms of service.

Final Answer

Standard z-score = (97 -96.2)/0.82= 0.9756

We now want area to the left

P( z=<0.9756) =  0.8354 = 83.54 percentile score
