A sample of 15 workers in a certain city showed the following hourly wages in dollars) 140, 140, 125, 133, 135, 135, 140, 132, 130, 125, 140, 120, 125, 140, and 150 Find (a) the mean, (b) the median, and (c) the mode of the sample.

The mean is the average of the given numbers. The median is the number in the middle of a set of given numbers and the mode is the value that appears most frequently.

The numbers must first be organized in ascending order.

120, 125, 125, 125, 130, 132, 133, 135, 135, 140, 140, 140, 140, 140, 150

In order to find the mean, all the given numbers must be added and divided by the amount of given numbers.

120+125+125+125+130+132+133+135+135+140+140+140+140+140+150=2010

2010/15=134

The mean is 134.

In order to find the median, eliminate numbers on each side until one number is remaining.

The median is 135.

In order to find mode, count each number and find the largest frequency of each.

The mode would be 140.
