Chapter 13.1, Problem 12PPS

To determine

To find: Which measure of central tendency might the store wants to use to attract people to work.

Answer to Problem 12PPS

The store wants to use the central tendency mean to attract people to work.

Explanation of Solution

Given:

The hourly wages of employees in a small store are $\$7,\$24,\$8,\$10,\$6,\$8,\text{ and \$8}$

Calculation:

The given data is $\$7,\$24,\$8,\$10,\$6,\$8,\text{ and \$8}$

Find mean, medina and mode of this data.

  $\begin{array}{c}\text{mean}=\frac{\text{Sum of observations}}{\text{Number of observtions}}\\ \\ =\frac{7+24+8+10+6+8+8}{7}\\ =\frac{71}{7}\\ =10.1\end{array}$

In order to find the median arrange this data in numeric order

  $6,7,8,8,8,10,24$

The number of data is seven which is odd.

So, median is given by $8$

Now, in the given set of data, the number 8 occurs thrice.

So, the median is 8.

Among the mean, median and mode, the greatest is mean.

Therefore, the store wants to use the central tendency mean to attract people to work.
