    2. The weight of potato chips in a medium-size bag is stated to be 10 ounces. The amount that the packaging machine puts in these bags is believed to have a Normal model with mean 10.2 ounces and standard deviation 0.12 ounces. Some of the chips are sold in “bargain packs” of 3 bags. What’s the probability that the mean weight of the 3 bags is below the stated amount? Please show all work. Please no handwritten work, just typed.
