Question

Suppose the true proportion of voters in the county who support a new fire district is 0.61. Consider the sampling distribution for the proportion of supporters with sample size n = 90.

What is the mean of this distribution?

What is the standard error (i.e. the standard deviation) of this sampling distribution, rounded to three decimal places?

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.
