Answer 1

Step-by-step-Explanation:

Given that:y-2a,y-a,y,y+a,y+2a

To find: Mean

Solution:

We know that formula of mean

$\bold{\blue{Mean = \frac{Sum \: of \: all \: observation}{Total \: observation}}}$

Observation/Data= y-2a,y-a,y,y+a,y+2a

Number of observation= 5

$Mean = \frac{y - 2a + y - a + y+y + a + y + 2a}{5} \\ \\ Mean = \frac{5y - 3a + 3a}{5} \\ \\ Mean= \frac{5y}{5} \\ \\ Mean = \frac{ \cancel5 \: y}{\cancel5} \\ \\ \bold{Mean = y}$

Mean of given data is y.

Option 4 is correct.
