Question

an arthimetic mean of a frequency distribution is 5 if each frequency is multiplied by three then what will be the arthimetic mean​

Answer 1

Answer:

arithmetic mean is 3 × 5= 15

Answer 2

Answer:

The answer is 15

Explanation:

Given the mean of 20 items are 5

The sum is 212. The mathematics mean is 212 divided by means of 4, or 53.The mathematics mean is a measure of vital tendency.

It allows us to characterize the middle of the frequency distribution of a quantitative variable via thinking about all of the observations with the equal weight afforded to every (in evaluation to the weighted mathematics suggest).
