<PRE><B>Question 453135</B>
assume body temp of healthy adults are normally distributed with a mean of 98.20F and a standard deviation of 0.62F. what body temperature is the 95th and 5th percentile??
----------------------
Find the z-value with a 95% left-tail: Ans: z = 1.645
----
Find the z-value with a 5% left-tail: Ans: z = -1.645
-----
95%ile = 1.645*0.62+98.2 = 99.22 degrees
---
5%ile = -1.645*0.62+98.2 = 97.18 degrees
