1.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 25 miles per hour (mph) for a site to be acceptable. Recently, the organization conducted wind speed tests at a particular site. Based on a sample of 43 wind speed recordings (taken at random intervals), the wind speed at the site averaged 25.8 mph, with a population standard deviation of 4.2 mph. To determine whether the site meets the organization's requirements, consider the test, H0: µ = 25 vs. Ha: µ > 25, where µ is the true mean wind speed at the site and ΅= .01. Suppose the value of the test statistic were computed to be 1.25. State the conclusion. A) At ΅= .01, there is sufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph. B) At ΅= .01, there is insufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph. C) We are 99% confident that the site meets the organization's requirements. D) We are 99% confident that the site does not meet the organization's requirements.

if suppose the value of the test statistics computed to be 1.25 then our most logical conclusion would be that A) At ΅= .01, there is sufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph.

Step-by-step explanation:

Because we cannot say for certain at 99% whether the site will meet the requirement or not but at 0.1 we are certain and can conclude that the true mean wind speed exceeds 25mph based on the hypothesis claimed.

True mean simply refers to the population or sample mean of what is in question.

mean can simply mean the average of a certain set of numbers.
