Answer:

C. 187

Step-by-step explanation:

Givens

  • The sample is formed by 187 bowlers.
  • The population is formed by 999 bowlers.

If [tex]x[/tex] represents a mean, it would be a sample mean.

When we develop statistics studies, we define a sample, which represents a sub-group of the population. All statistics analysis are applied to the sample, because it's easier to deal with. So, to develop a correct analysis, the sample has to represent the population, it has to be large enough to generalise its results.

That's why the mean [tex]x[/tex] would represent the sample 187.
The correct answer is C.

Hope this helps.
