Question

Consider the following two hypothesis testing scenarios for the population proportion (p) and corresponding studies:

I. The UCLA Internet Report (February 2003) estimated that roughly 8.7% of internet users are extremely concerned about credit card fraud when buying online. A study was designed in order to examine whether that proportion has changed since.

II. The UCLA Internet Report (February 2003) estimated that roughly 8.7% of internet users are extremely concerned about credit card fraud when buying online. In light of the increasing problem of spyware, a study was designed in order to examine whether that proportion has increased since.

Assume that the two studies (I and II) used the same data, and that the p-value of the test corresponding to study I was found to be .024. The p-value of the test corresponding to study II:

	A.	Must be 0.012
	B.	Must be 0.048
	C.	Must also be 0.024, since both studies used the same data.
	D.	Cannot be determined based on the information provided by the problem
