Chapter 2.2, Problem 2.33E

To determine

To find: the mean and explain it.

Answer to Problem 2.33E

  $\mu =1600$

Explanation of Solution

Given:

Seven person’s metabolic rates

1792 1666 1362 1614 1460 1867 1439

Formula used:

  $\mu =\frac{{\displaystyle \sum x}}{n}$

Calculation:

  $\begin{array}{l}\mu =\frac{{\displaystyle \sum x}}{n}\\ =\frac{1792+1666+1362+1614+1460+1867+1439}{7}\\ =\frac{11200}{7}\\ =1600\end{array}$

Metabolic rate is major in studies of weight gain, exercise and dieting. On the basis of given metabolic rates of seven men, calculating the mean which is sum of all values divided by the number of values which is 1600. It shows that a person has a metabolic rate of 1600 calories per day.
