Chapter 12, Problem 9PT

To determine

To find: the best measure of central tendency to represents the data and find the measure.

Answer to Problem 9PT

The best measure of central tendency to represent the data is mean of the data and the value of mean is $\text{4}\text{.08}$ .

Explanation of Solution

Given information:

The number of items on a dayis : $3,5,4,3,4,5,5,3,2,3,2,10$

Calculation: to represents the data the mean measurement is best because this is the number of items so the mean value represents the average number of items on a day,

To find the mean add all data and divide it by the number of data,

  $\begin{array}{l}\text{mean}=\frac{3+5+4+3+4+5+5+3+2+3+2+10}{12}\\ \text{mean}=\frac{49}{12}\text{ [add]}\\ \text{mean=4}\text{.08 [divide]}\end{array}$

Thus, the mean value is $\text{4}\text{.08}$ .
