What is a sampling distribution?

A sampling distribution is a statistical probability distribution derived from a larger number of samples gathered from a certain population. The sampling distribution of a given population is the distribution of frequencies of a range of possible outcomes for a population statistic.

The sample size multiplied by the population mean yields the expected value of the sample total.

The anticipated value is calculated in statistics and probability analysis by multiplying each conceivable outcome by the likelihood that each outcome will occur and then adding all of those values.

In this case, the the proportion of people who order coffee with their dinner is 0.9. This is the expected value.
