Question

find the mean of the following 3,5,2,15,10​

Answer 1

Answer:

The mean of the given observations is 7.

Step-by-step explanation:

Solution -

Mean is also known as the average of the given observations.

The observations we are given = 3,5,2,15,10

The formula for finding mean of any observations is -

$\boxed{\sf{Mean = \frac{Sum \: of \: Observations}{No. \: of \: Observations}}}$

• Sum of observations =

⇒ 3 + 5 + 2 + 15 + 10

⇒ 8 + 2 + 15 + 10

⇒ 20 + 15

⇒ 35

• Number of observations = 5

★ Mean =

⇒ 35/5

⇒ 7

Mean = 7

Therefore, the mean of the given observations is 7.

Answer 2

Mean = 7
