A pharmaceutical company is considering the purchase of new bottling machines to increase its efficiency. The factory currently uses machines that fill cough syrup bottles whose volume of medicine has a standard deviation of 1.6 mL. The new machine the company is considering was tested on 30 bottles, producing a batch with a standard deviation of 1.25 mL. Does this machine produce a variance of less than 1.6 at the 0.05 significance level? State the TS and test decision.
