Question

A clinic took temperature readings of 250 flu patients over a weekend and discovered the temperature distribution to be Gaussian, with a mean of 101.20°F and a standard deviation of 0.9750. Use this normal error curve area table to find the following values. (a) What is the fraction of patients expected to have a fever greater than 103.35°F? Incorrect. See the lower panel for more information. Number 0.0026 (b) What is the fraction of patients expected to have a temperature between 100.62°F and 102.47°F? Number 0.5209

Explanation / Answer

Data given:

Mean, m = 101.2

Standard Deviation, S = 0.975

(a)

Calculating z-score:

z = (X-m)/S = (103.35-101.2)/0.975 = 2.205

The corresponding p-value for this z-score is:

p = 0.013
