Question 929472: In a random sample of 250 voters interviewed while exiting from polling places throughout a state, 145 said they voted for the reelection of the incumbent governor. Let p denote the true proportion of all registered voters in the state who would vote for the incumbent governor. In a test of the hypotheses: H0: p = .5 versus H1: p ╪ .5, the p-value for the test is

Note: In computing your test statistic, round off the denominator to the nearest thousandths

t(.58) = (.58-.50)/(.50*.50/250) = .08/ .032
P(t > 2.5) = normalcdf(2.5, 100) = .0062
C.
