Bags of a certain brand of tortilla chips claim to have a net weight of 14 ounces. Net weights actually vary slightly from bag to bag. Assume net weights are Normally distributed. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised and so intends to test the hypotheses H0: μ = 14 versus Ha: μ < 14. To do this, he selects 16 bags of...

5) The net weights of potato chips actually vary slightly from bag to bag. A quality technician randomly selects 10 bags of chips and the net weights (in ounces) are 13.82, 13.85, 14.01, 14.03, 13.88, 14.02, 14.04, 13.84, 13.84, 13.89. Use a = 0.1. a.
