Question

	State run	Privately owned
Sample Size	16	26
S. d.	0.344	0.264

Determine an 99% confidence interval for the ratio of the population s. d. of whiskey prices for state-run stores and privately owned stores.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
