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,
[tex]45=\frac{sum}{5}[/tex]
[tex]Sum=45*5[/tex]
[tex]Sum=225[/tex]
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).
