The national aeronautics and space administration (nasa) has been working with utilities throughout the nation to find sites for large wind machines for generating electric power. wind speeds must average more than 15 miles per hour (mph) for a site to be acceptable. recently nasa conducted tests at a particular site under construction for a wind machine. based on a sample of n = 100 wind speed recordings (taken at random intervals) at the site, the wind speed average was 14.5 mph, with a standard deviation of 3 mph. to determine whether the site meets nasa requirements, consider the test, h0: μ ≤ 15 vs. ha: μ > 15, where μ is the true mean wind speed at this site and α = 0.05.step 1 of 2: calculate the value of the test statistic. round your answer to four decimal places.
