14. A potato chip manufacturer regularly inspects bags of chips to make sure there aren't too many below the advertised weight of 32 ounces. Each hour they take a random sample of 10 bags of chips, calculate the first quartile (Q.) for the sample of weights, and adjust the machine if Q, is significantly less than 32 ounces. (a) Define the parameter of interest and state the hypotheses the manufacturer wants to test. Q1 = H,: H : Here are the weights of 10 bags from one random sample. Bag Number Weight (ounces) 31.1 | 31.8 34.6 33..3 29.9 30.2 321 326 31.9 31.2 2. 3 4. 6. 8. 9. 10
