Question

If a sample of 362 customers is taken from a population of 5530 customers,
the sample variance, s? is the variance of how many of the customers' ages?
A. Neither 362 nor 5530
B. 5530
C. 362
D. Both 362 and 5530

Answer 1

Using concepts of sample and population, it is found that the sample variance is representative of 362 and 5530 customers ages, option D.

------------------------

In sampling, the information is taken from a sample, and is used to estimate it for the whole population.

• In this problem, we have a sample of 362 and a population of 5530 customers.
• The sample variance $s^2$ is calculated from the sample, and used as an estimate for the population variance. Thus, it can be said that it represents both 362 and 5530 customers, and the correct option is D.
