Question

use software or a calculator to find the range, variance, and standard deviation of the following body temperatures, in degrees fahrenheit, taken at 12:00 a.m.
click the icon to view the table of body temperatures.
the range of the data set is 3.40°f
(round to two decimal places as needed)
the standard deviation, s, of the data set is 0.66°f
(round to two decimal places as needed)
the variance, s², of the data set is
(round to two decimal places as needed)

Explanation:

Step1: Recall the formula for variance

The variance \(s^{2}\) is the square of the standard deviation \(s\).

Step2: Calculate the variance

Given \(s = 0.66\), then \(s^{2}=(0.66)^{2}\)

$$s^{2}=0.66\times0.66 = 0.4356\approx0.44$$

Answer:

\(0.44\)
