Let x, y and ...

Question

Question 1
Let x, y and z be three observations. The mean of these observations is
(a) $\frac{x \times y \times z}{3}$
(b) $\frac{x + y + z}{3}$
(c) $\frac{x - y - z}{3}$
(d) $\frac{x \times y + z}{3}$

Solution

(b)
Here, x, y and z be three observations.
We know that, $M e a n = \frac{S u m o f o b s e r v a t i o n s}{N u m b e r o f o b s e r v a t i o n s}$
$= \frac{x + y + z}{3}$
