Answer 2

Given:

No. of scores = 5

Mean of 5 scores = 45

To find:

Total value of the scores.

Solution:

The mean of a set of scores or values is the arithmetic average of these values. It is given by the formula:

Mean = Sum of values/No. of values

Here, the no. of scores is 5 and mean of these scores is given by 45. We need to find the total sum of the scores.

Substituting these values in the above formula, we get,

$45=\frac{sum}{5}$

$Sum=45*5$

$Sum=225$

From the options given, option (d) is the correct answer.

225 is the total value of 5 scores whose mean is 45. The correct option is (d).
