The national unemployment rate in a recent month was 4.9 percent. You think the rate may be different in your city, so you plan a sample survey that will ask the same questions as the Current Population Survey. Consider p as the local employment rate. Identify the null and the alternative hypotheses that you will test to see if the local rate differs significantly from 4.9 percent.
H0: p = 0.049, Ha: p < 0.049
H0: p = 0.049, Ha: p = 0.049
H0: p = 0.049, Ha: p > 0.049
