When chip bags are produced, the weight listed on the bag can vary from bag to bag. Quality control specialists are there to take a random sample of the chip bags to determine if they are being under filled. The machine operates with a standard deviation of 0.85 ounces and the chip bags are labeled with 12 ounces. If the mean weight of 20 bags of chips is 11.5 ounces or less, the machine will be stopped and recalibrated. Given the situation, what is the probability that the specialist will stop the machine for calibration when it actually is filling up correctly? A. 0.0043 B. 0.0467 C. 0.0897 D. 0.1121 E. 0.9957
