Question

A cereal box is labeled as containing 16 ounces. Suppose the production line manager tests to determine whether the average weight of cereal in a box is less than 16 ounces. He concludes that the null hypothesis should not be rejected. Which of the following is a correct statement

a. The production line appears to be filling the cereal boxes with at least 16 ounces of cereal. b. The weights in each box must have been recorded incorrectly. c. The company should either change the label or add more cereal to each box in the production line. d. No conclusions regarding the weight of cereal in a box can be drawn from the test.

Explanation / Answer

Answer is d.) No conclusions regarding the weight of cereal in a box can be drawn from the test.

Because even if the conclusion is that the null hypothesis should not be rejected, it doesn't mean that the null hypothesis is correct. Since a hypothesis test only assesses whetther the available evidence exists to reject the null hypothesis and does not determine which hypothesis is true or even which hypotheis is more likely.
