Question

A national organization has been working with utilities throughout the nation to find sites for large wind machines that generate electricity. Wind speeds must average more than 13 miles per hour (mph) for a site to be acceptable. Recently, the organization conducted wind speed tests at a particular site. To determine whether the site meets the organization's requirements, consider the test, where μ is the true mean wind speed at the site. Suppose the observed significance level (p-value) of the test is calculated to be 0.024 Interpret this result.

		At alpha = .01, we fail to reject the null hypothesis.
		At alpha = .05, we fail to reject the null hypothesis.
		At alpha = .001, we reject the null hypothesis.
		At alpha = 0.25, we fail to reject the null hypothesis.
