Use the given data to find the minimum sample size required to estimate the population proportion. Margin of error: 0.015; confidence level: 90%; p and q unknown

Use the formula. It's just 'plug and chug'.

n=p(1-p)\left(\frac{z}{E}\right)^{2}

If p is unknown, assume p=0.5

In this case, E=.015, \;\ z=1.645, \;\ p=.5

Round up to the nearest whole number.
