You are using a sample of size 150 to conduct a hypothesis test in which you want to determine whether a certain population proportion $\pi$ has decreased since last year.If the null hypothesis is $\pi$ .5 and the p-value for the test turns out to be .0324, you should conclude, at the .05 significance level, that the population proportion has, in fact, decreased.

Question

You are using a sample of size 150 to conduct a hypothesis test in which you want to determine whether a certain population proportion  $\pi$ has decreased since last year.If the null hypothesis is  $\pi$ > .5 and the p-value for the test turns out to be .0324, you should conclude, at the .05 significance level, that the population proportion has, in fact, decreased.

Quizplus · Accepted Answer

Since the p-value (.0324) is less than the significance level (.05), you reject the null hypothesis, concluding there is significant evidence that the population proportion has decreased.
