Final answer:
To find the number of scores in the population, we can use the formula n = (XX - μ^2) / σ^2, where n is the number of scores in the population. However, without the value of σ^2, we cannot calculate the number of scores.
Step-by-step explanation:
To find the number of scores in the population, we can divide the sum of squares (XX) by the square of the standard deviation (σ2). In this case, XX = 40 and μ = 8. Since σ2 is not given, we cannot determine the exact number of scores in the population. However, we can use the formula:
n = (XX - μ2) / σ2
where n is the number of scores in the population. Without the value of σ2, we cannot calculate the number of scores.
