Is the randomization condition satufet? OA Yes, there is definitely evidence to believe that the bags of chips were sampled at random O No, the bags were not selected at random, it is reasonable to think that these bags are representative of all bag of chips OC. We don't know that the bags of chips were sampled at random, but it is reasonable to think that they were is the 10% condition and OA Ns, bags of chips are more than 10% of bags of chips OBY bags of chips are less than 10% of all bags of chips OC. No tags of chips are less than 10% of wil bags of chips OD 6 bags of this we more than 10% of all bags of chip Is the nearly al condition OA Yes, the sample of bags of chips is primately normal O No, the sample of bags of this is not approximately normal OC We don't know, since the sample of bag of chipe is mal we cannot determine the distribution is approximately omal or not Find the mean and standard deviation of the observed weights y grama Round two decal places as needed) grams (Hound to the decimal places as needed.) elle a confidence trval for the mean wel of such as of his
