Question

Suppose that cans of a certain commercial beverage are labeled as containing 12 ore A company technician weighed the content of 7 randomly chosen cans, and found the mean weight to be 12.12. Assume that the ans are filled so that the actual amounts are normally distributed with a means of 12.00 and a standard deviation of 0.1 oz. Find the probability that sample of 7 cans will have a mean amon of at least 12.12 oz You may round your answer to three decimal places

Answer 1

Here we have: n=7 M =12 r20.1 Pla 31212) - plan ) =P(223.17) = 1- P(Z <3-17) =1-0.9992 = 0.0008 = 10.001) Round to three decimal place)
