Quality Assurance (Read this entire document before beginning the assignment) You work for Frito-Lay in the quality assurance lab. You have just taken several samples from the Doritos production line for the 32 ounce bag of Nacho Cheese Doritos. You have 50 bags of Nacho Cheese Doritos sampled from the first shift of production for the day. You have weighed each bag and the weights of the bags are listed below. Sample bag weights for fty 32 oz. bags of Nacho Cheese Doritos (N=50) 31.51 30.94 32.24 30.75 30.77 33.11 32.02 32.97 30.48 32.22 33.16 32.41 31.26 33.45 32.36 31.02 31.13 30.51 33.11 31.37 30.67 31.42 33.12 31.24 32.15 32.51 31.84 30.92 33.11 32.12 30.61 31.24 32.04 31.25 31.93 32.05 31.32 31.12 31.03 29.87 31.27 32.06 31.03 32.03 32.19 31.17 32.01 31.45 32.31 31.15 1. You want to determine if the average weight of the actual sample bags is signicantly different from the desired weight. Is any difference due to random error (just dumb luck) or due to some other potential cause? Should you test a NULL or DIRECTIONAL hypothesis; and EXPLAIN WHY (using correct nomenclature)
