Question

An opinion poll asks a sample of 500 adults whether they favor giving parents of school-age children vouchers that can be exchanged for education at any public or private school of their choice. Each school would be paid by the government on the basis of how many vouchers it collected. Suppose that in fact 45% of the population favor this idea. What is the probability that more than half of the sample are in favor? (Assume that the sample is an SRS.)

Step 1

1 of 8Given:

$\begin{aligned} n&=\text{Sample size}=500 \\ p&=\text{Population proportion}=45\%=0.45 \end{aligned}$

We need to determine the probability $P(\hat{p}>0.5)$, as more than half corresponds with more than 50%.
