Question

question 4 of 10
the estimate obtained from a sample of which of the following sizes would most likely be closest to the actual parameter value of a population?

a. 300
b. 90
c. 30
d. 150

Explanation:

Step1: Recall Sampling Theory

In sampling, a larger sample size generally gives a more accurate estimate of the population parameter (due to the Law of Large Numbers, which states that as sample size increases, the sample statistic approaches the population parameter).

Step2: Compare Sample Sizes

We have sample sizes: 30 (C), 90 (B), 150 (D), 300 (A). Among these, 300 is the largest.

Answer:

A. 300
