Suppose we have a set of body temperatures with a mean of 98.6 degrees, and a sample standard deviation of 1.0 degree. Assuming a normal distribution of body temperatures in the larger population, between what two values should 95% of all temperatures lie? Show all work
Z = (score-mean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion (.475 each way) to get the Z scores. Insert values above and calculate.
