19.9
201
20.3
20.6​

Answer 1

The right answer is 19.9

Step-by-step explanation:

Given data set is;

(18, 23, 17, 25, 15, 18, 18, 16, 27, 25, 18, 19)

Sum of terms = 18+23+17+25+15+18+18+16+27+25+18+19 = 239

Number of terms in data set = 12

Average = $\frac{Sum\ of\ terms}{Number\ of\ terms}$

Average = $\frac{239}{12}$

Average = 19.91

The average of data set is 19.91

The right answer is 19.9
