Question

The FDA has established that the concentration of a certain pesticide in apples may not exceed 10 ppb. A random sample of 100 apples from a major orchard had an average pesticide content of 10.03 ppb with a standard deviation of 0.12 ppb. Are the apples within the FDA requirement

Answer 1

Explanation:

(10.03 - 10)/(.12/sqrt 100) = 2.5

P(Z > 2.5) = .0062

p-value = .0062. The apples are not within the FDA requirement
