11. (5 points) A sample of 50 lenses used in eyeglasses yields a sample mean thickness of 3.10 mm and a sample standard deviation of .34 mm. The desired true average thickness of such lenses is 3.20 mm. Does the data strongly suggest that the true average thickness of such lenses is something other than is desired? Test the hypotheses using α = 0.05. Show all work that includes: stating the hypotheses, computing the value of the TS, finding the...
