Answer:
An approximate estimate of the standard deviation of the number of the points scored per game is of 5.79.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Suppose that the middle 95% of average scores in the NBA per player per game fall between 8.18 and 31.34.
This means that there is 4 standard deviations within this interval. So
[tex]4s = 31.34 - 8.18[/tex]
[tex]4s = 23.16[/tex]
[tex]s = \frac{23.16}{4}[/tex]
[tex]s = 5.79[/tex]
An approximate estimate of the standard deviation of the number of the points scored per game is of 5.79.
