question 13

Multiple Choice

In the equation for the standard deviation of the sampling distribution, $\frac{s}{\sqrt{n}}$ , where s is the standard deviation and n is the sample size, how could one get more precise estimates that differ less from one another?

• A) increase s to expand the distribution
• B) increase the sample size (n) because as the denominator increase the resulting value decreases
• C) decrease the sample size (n) because as the denominator decreases the resulting value decreases
• D) collect data that are not skewed
