The sampling distribution of the mean is more compact, with a smaller variance.

On basis of sample statistics derived from limited businfss incomplete sample information Make generalizations about the characteristics of a population Is there evidence to conclude that the population proportion of all hotels in the country satisfying the standards set by the Small Luxury hotels Association is greater than 0.
