A nаtiоnаl оrgаnizatiоn has been working with electric companies throughout the US to find sites for large windmills to generate electric power. Wind speeds must average more than 21 miles per hour (mph) for a site to be acceptable. Recently, the organization conducted tests at a particular site where windmills are under construction. Based on a sample of n = 40 wind speed recordings (taken at random intervals) at the site, the wind speeds averaged 23 mph with a standard deviation of 3.9 mph. To determine whether the site meets the organization's requirements, they want to test: Ho: μ = 21 mph Ha: μ > 21 mph using a significance level (α) = 0.01. Calculate the value of the test statistic needed to test the null hypothesis.
