Question

An investor claims that greater than 30% of companies are inadequately priced. She randomly samples 600 companies and 32% of them are inadequately priced. Is this sufficient evidence in favor of her claim that the percentage is greater than 30%?  The computed p-value is .1425. Find the z or t value for this test. At a significance level of .05, what decision should the investor make?

	A.	The z or t value is 0.027. There is not enough information to reach a conclusion.
	B.	The z or t value is 0.32. There is significant evidence to reject the null hypothesis and accept the claim that the percentage is greater than 30%.
	C.	The z or t value is 1.07. There is significant evidence to reject the null hypothesis and accept the claim that the percentage is greater than 30%.
	D.	The z or t value is 0.32. There is not significant evidence to reject the null hypothesis and accept the claim that the percentage is greater than 30%.
	E.	The z or t value is 1.07. There is not significant evidence to reject the null hypothesis and accept the claim that the percentage is greater than 30%.
