Question

Estimate the arithmetic mean of 5,6,7,8,8,10,10,10,12,12,13,19,19,19,20​

Answer 1

Answer:

THE ANSWER IS 11.86

Step-by-step explanation: If we should find a mean, we should add all these numbers and divide it by the total numbers.

IE: n=15, means there are 15 numbers in the question

so, MEAN= 5+6+7+8+8+10+10+10+12+12+13+19+19+19+20

_________________________________________________=

                                            15

178 divided by 15=   we get 11.86.

HOPE THIS WAS HELPFUL..
