Question

• A. $12$
• B. $24$
• C. $18$
• D. $30$

Answer 1

Answer: (C)

$18$

The given observations are : $8,12,16,10,22,4$
multiplying each observation by $3$ and the dividing each observation by $2$, we get: $12,18,24,15,33,6$
Mean $=$ $\frac{Sum}{Numberofobservations}$
Mean $=$ $\frac{12+18+24+15+33+6}{6}$ $=$ $\frac{108}{6}$ $=$ $18$
