Question

Suppose a university is considering a survey to determine the proportion of college graduates that move out of state after graduation. How many graduates must be surveyed to get a sample percentage with a margin of error of 1.9%? Use 95% confidence. 2,661 Use the following equation to find the sample size needed to estimate a proportion. $n = left(frac{z_{alpha/2}}{m} ight)^2 p(1 - p)$ If p is unknown use p = 0.5.

Use the following equation to find the sample size needed to estimate a proportion.
$n = left(frac{z_{alpha/2}}{m}
ight)^2 p(1 - p)$
If p is unknown use p = 0.5.
