Coca-Cola has a manufacturing process that meets the requirements that the standard deviation of amount of color in a 12 ounce can be 0.115 ounces. A new process has been introduced to the factory, but it is first tested to see if it meets the requirement. 10 cans are randomly selected and the volume is measured. Here is the raw data 12.078, 11.851, 12.108, 11.760, 12.142, 12.147, 12.238, 11.779, 12.397, 11.504 A) is there enough evidence to support or reject the claim? b) What do the results suggest about the new filing process? Because the sample standard deviation is (lower/about the same/higher) than the target, it suggests the new process has (less/more/about the same) variation than the old. The new process is (about the same/ better/ worse) than the old one.
