Given:
You scored 12, 8, 15, and 21 points during your first four basketball games.
To find"
The mean score per game.
Solution:
We have,
Observations =12, 8, 15, and 21 points
Number of observations = 4
We know that,
[tex]\text{Mean}=\dfrac{\text{Sum of the observations}}{\text{Number of observations}}[/tex]
The mean score per game is
[tex]\text{Mean}=\dfrac{12+8+15+21}{4}[/tex]
[tex]\text{Mean}=\dfrac{56}{4}[/tex]
[tex]\text{Mean}=14[/tex]
Therefore, the mean score per game is 14 points.
