Answer

Explanation:

Step1: Identify the data values

The data values from the dot - plot are: 125, 140, 140, 155, 155, 160, 175.

Step2: Calculate the sum of data values

$125 + 140+140 + 155+155+160+175=1050$.

Step3: Calculate the number of data points

There are 7 data points.

Step4: Calculate the mean

The mean $\bar{x}=\frac{1050}{7}=150$. The mean is a measure of the center of a distribution.

Answer:

150 ... center
