Does the label “GLUTEN FREE” guarantee that a food hasabsolutely NO gluten? FDA guidelines state a food must contain less than 20 partsper million of gluten to qualify as gluten free. (So some foods containing somegluten may legally qualify as gluten free.) A brand of crackers claiming to begluten free was tested ; for a sample of 7 batches of these crackers, the gluten levelsin parts per million were: 9 20 14 22 14 12 15Perform a hypothesis test to determine if the average gluten content is less than 20parts per million so that the manufacturer can support its claim that the crackerscan be represented as gluten free. Use a 3% level of significance.

A new process has been designed to make ceramic tiles. The goal is to have no more than 5% of the tiles be nonconforming due to surface defects. A random sample of 1000 tiles is inspected. Let X be the number of nonconforming tiles in the sample. a) If 5% of the tiles produced are nonconforming, what is P(X ≥ 75)? b) Based on the answer to part (a), if 5% of the tiles are nonconforming, is 75 nonconforming tiles out of 1000 an unusually large number? c) If 75 of the sample tiles were nonconforming, would it be plausible that the goal had been reached? Explain. d) If 5% of the tiles produced are nonconforming, what is P(X ≥ 53)? e) Based on the answer to part (d), if 5% of the tiles are nonconforming, is 53 nonconforming tiles out of 1000 an unusually large number? f) If 53 of the sample tiles were nonconforming, would it be plausible that the goal had been reached? Explain.
