Chapter 15: Problem 63

Find the arithmetic mean of each group of numbers. 19,24,20,17,23,17

Short Answer

Expert verified
The arithmetic mean of the group of numbers 19,24,20,17,23,17 is \(20\).

Step by step solution

01

Add the numbers

To begin, we will add all the given numbers together: \(19+24+20+17+23+17\).
02

Calculate the sum

Now, we can calculate the sum of the numbers: \(19+24+20+17+23+17=120\).
03

Count the number of values in the group

Next, we need to determine the total number of values in the group. There are six numbers in the group: 19, 24, 20, 17, 23, and 17.
04

Divide the sum by the number of values in the group

Now that we know the sum of the numbers (120) and the number of values in the group (6), we can find the arithmetic mean by dividing the sum by the number of values: \(\frac{120}{6}\).
05

Calculate the arithmetic mean

Finally, we calculate the arithmetic mean by dividing 120 by 6: \(\frac{120}{6}=20\). So the arithmetic mean, or average, of the group of numbers 19, 24, 20, 17, 23, and 17 is 20.
