Gator Beverages produces soda cans that are sold in cans labeled as having 12 ounces of soda. If the soda content is below 12 ounces, the customer is being unduly denied product they have paid for. Filling each can with more than 12 ounces costs the company money since it essentially means giving away free product. Accordingly, Gator Beverages have set specification of 11.8 and 12.2 ounces for the volume of soda in a can. Currently the cans are filled automatically by a filling machine and they have an average volume of soda of 11.92 ounces. What is the maximum standard deviation that the process can have that would allow Gator beverage to claim they have a six- capability? 0.0467 0.0200 0.0333 0.0133 0.0383 None of the other answers are within 0.0025
