You are using a sample of size 225 to conduct a hypothesis test in which you want to determine whether a certain population proportion $\pi$ has changed since last year.If the null hypothesis is $\pi$= .25 and the p-value for the this two-tailed test turns out to be .0263, you should conclude, at the .05 significance level, that the population proportion has, in fact, changed.

Since the p-value (.0263) is less than the significance level (.05), we reject the null hypothesis, concluding that the population proportion has changed.
