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 10 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 and  Suppose the observed significance level (p-value) of the test is calculated to be  Interpret this result.

Answer 1

H0: Null Hypothesis: 10 ( Wind speeds do not average more than 10 miles per hour )

HA: Alternative Hypothesis: 10 ( Wind speeds average more than 10 miles per hour ) (Claim)

Question:

Interpret this result.

If the observed p-value of the test is greater than the significance level , the difference is not significant. Fail to reject null hypothesis. The data do not support the claim that wind speeds average more than 10 miles per hour. The site does not meet the organization's requirements,

If the observed p-value of the test is less than the significance level , the difference is significant. Reject null hypothesis. The data support the claim that wind speeds average more than 10 miles per hour. The site meets the organization's requirements,
