Question

the sum of deviations of 25 observations measured from 45 is _55.find out the A.M of the observations​

Answer 1

The A.M of the observations is 2.2

To Find:

the A.M of the observations​

Given:

The sum of deviations of 25 observations from the mean is 55.

Solution:

The sum of deviations of 25 observations from the mean is 55.

To find the mean of the observations, we can use the formula:

mean = (sum of observations) / (number of observations)

We know that the sum of the deviations is 55, and the number of observations is 25.

To find the sum of the observations, we can use the formula:

sum of deviations = n * mean

Where n = number of observations = 25

55 = 25 * mean

mean = 55/25

mean = 2.2

Therefore, the mean of the observations is 2.2

So, the A.M of the observations is 2.2

Answer 2

Answer:

The A.M of the observations is 2.2

Step-by-step explanation:

Step 1: The sum of deviations of 25 observations from the mean is 55.

The sum of deviations of 25 observations from the mean is 55.

To find the mean of the observations, we can use the formula:

mean = (sum of observations) / (number of observations)

We know that the sum of the deviations is 55, and the number of observations is 25.

Step 2:To find the sum of the observations, we can use the formula:

sum of deviations = n * mean

where n = number of observations = 25

55 = 25 * mean

mean = 55/25

mean = 2.2

Therefore, the mean of the observations is 2.2

So, the A.M of the observations is 2.2.
