Explanation:

Givens

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

If
`x` 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
`x` would represent the sample 187.
