The fun size of a Snickers bar is supposed to weigh 20 grams. Because the penalty for selling candy bars under their advertised weight is severe, the manufacturer calibrates the machine so the mean weight is 20.1 grams. The quality-control engineer at MMMars, the Snickers manufacturer, is concerned about the calibration. He obtains a random sample of 10 candy bars, weighs them, and obtains the data shown in Table. Should the machine be shut down and calibrated? Because shutting down the plant is very expensive, he decides to conduct the test at the α = 0.01 level of significance.Weight: 19.619.920.521.520.620.620.319.719.5
