A firm is bidding to provide T-shirts to football players of the CFL. A sample of 11 slotbacks gave a mean weight of 195.0 lb and standard deviation of 14.3 lb. The firm sells a shirt with just enough stretchiness to fit the variation of sizes of quarterbacks. To test if it would be reasonable to assume that this shirt could also fit all of the slotbacks if you know that the mean for quarterbacks is 192.7 lb and the standard deviation for quarterbacks is 11.7 lb : a. Test if the stretchiness of the shirt is sufficient to fit the spread in the size of slotbacks. b. Test if the average size of the shirts will fit the average size of the slotbacks.
