The USA Corps of Engineers is considering two different loaders that move large amounts of fill per load. As a result, they wish to determine if the variances for the two pieces of equipment differ. Max B. took a sample of 9 hourly readings from the Charleston Company loader and a standard deviation of 2.8 tons was found. A sample of 10 hourly readings from the KaBuki loader showed a standard deviation of 1.2 tons. You may choose your own Type I error for the test.
