Question

Estimate the Arithmetic mean of the following

1) 5,6,7,8,8,10,10,10,12,12,13,19,19,19,20

Answer 1

Answer:

12.1428571

Step-by-step explanation:

The following data is, 5,6,7,8,10,10,10,12,12,13,19,19,19,20

Sum of observation = 5+6+7+8+10+10+10+12+12+13+19+19+19+20 = 170

Total number of values in the data = 14

then the arithmetic mean = Sum of observations/ Total no of values in the data

= 170/14

= 12.1428571
