Question
Students investigating the packaging of potato chips purchased 6 bags of chips marked with a net weight of 28.2 grams. They carefully weighed the contents of each bag recording the following weights (in grams): 29.4, 28.3, 29.4, 287, 289, 28.6. Click the icon to view the t table. a) Do these data satisfy the assumptions for inference? Is the randomization condition satisfied? 0 A. We don't know that the bags of chips were sampled at random, but it is reasonable to think that they were. O B. No, the 6 bags were not selected at random, but it is reasonable to think that these bags are representative of all bags of chips. O C. Yes, there is definitely evidence to believe that the bags of chips were sampled at random. Is the 10% condition satisfied? A. No, 6 bags of chips are less than 10% of all bags of chips. O B. Yes, 6 bags of chips are less than 10% of all bags of chips. O c. Yes, 6 bags of chips are more than 10% of all bags of chips. O D. No. 6 bags of chips are more than 10% of all bags of chips. Is the nearly normal condition satisfied? O A. Yes, the sample of 6 bags of chips is approximately normal. B. We don't know, since the sample of 6 bags of chips is small we cannot determine ifthe distribution is approximately normal or not O C. No, the sample of 6 bags of chips is not approximately normal.Explanation / Answer
Solution:-
a) => option B.
=> option B.
=> option A.
b) y = 28.88 grams
s = 0.45 grams
c) 6-1 = 5, a = 2.571
28.88-2.571(0.45/sqrt 6) = 28.4
28.88+2.571(0.45/sqrt 6) = 29.3
d) option A.
e) option C.
