Chapter 7.1, Problem 23E

To determine

To identify the correct option.

Answer to Problem 23E

The correct answer is (c).

Explanation of Solution

Given information:

Size of the random sample, $n=500$

Size of the population $=5,000,000$

Know that a descriptive measure for a population is known as a parameter. A descriptive measure for a sample is known as a statistic.

Also, a simple random sample has roughly the same variability as the population of that sample.

Thus, the variability of the estimate will be about the same as the variability for a sample of size $n=500$ from a population of size 50,000,000.

Hence, the correct answer is (c).
