Question

A.M of 30,20,32,16,27,32 is

Answer 1

Step-by-step explanation:

Given numbers are 30,20,32,16,27,32

Arithmetic mean= sum of observations/no.of observations

=30+20+32+16+27+32/6

=157/6

=26.12

Hope it may help you and if u like my explanation plz select me as a best brainlist

Answer 2

Answer:

Concept:

The arithmetic mean is the simplest and most widely used measure of average or mean. It simply means taking the sum of a group of numbers and then dividing that sum by the number of numbers used in the row.

Find:

We have find the A.M.

Given:

A.M of 30,20,32,16,27,32 is

Step-by-step explanation:

In statistics, the arithmetic mean (AM) or called the mean is the ratio of the sum of all observations to the total number of observations. The arithmetic mean can also inform or model concepts outside of statistics. In a physical sense, the arithmetic mean can be thought of as the center of mass. From the mean of a data set, we can think of the average distance of the data points from the mean as the standard deviation. The square of the standard deviation (ie variance) is analogous to the moment of inertia in a physical model.

The arithmetic mean is the simplest and most widely used measure of average or mean. It simply means taking the sum of a group of numbers and then dividing that sum by the number of numbers used in the row. For example, take the numbers 34, 44, 56, and 78. The sum is 212. The arithmetic mean is 212 divided by four, or 53.

Given numbers are 30,20,32,16,27,32

$Arithmetic \: mean= \frac{sum \: of \: all \: observation}{no. \: of \: observation}$

$Arithmetic mean= \frac{30 + 20 + 32 + 16 + 27 + 32}{6}$

$Arithmetic \: mean = \frac{157}{6}$

$Arithmetic \: mean= \: 26.12$

Hence A.M of 30,20,32,16,27,32 is 26.12
