When interviewing women teachers in Georgia, I plan to ask this following question: "Have you experienced sexual discrimination as a teacher in Georgia?" Research in other states suggest that about $75 \%$ of women teachers claim to have experienced some form of sexual discrimination in the workplace. For this study, set your confidence level of $95 \%$. Also, there are about 15,000 women teachers in Georgia. (Suppose we did not know that $75 \%$ will likely claim discrimination, what size sample would then be needed?)

Responses can take form of yes/no, so sample size for proportions can be used. We know from previous research to expect about $75 \%$ to experience sexual discrimination, and alpha $=.05$ with a population of about 15000 women teachers. Below are sample sizes needed for this study. (Note sample sizes needed in parentheses if the we did not know that $75 \%$ are expected to claim discrimination.)
$\begin{gathered} \text { Alpha }=.05 \\ \pm=1 \%, \mathrm{n}=4867(5856) \\ \pm=2 \%, \mathrm{n}=1608(2070) \\ \pm=3 \%, \mathrm{n}=760(997) \\ \pm=4 \%, \mathrm{n}=438(578) \\ \pm=5 \%, \mathrm{n}=283(375) \end{gathered}$
