Question

The makers of Mini-Oats cereal have an automated packaging machine that is set to fill boxes with 24.5 ounces of cereal (as labeled on the box). At various times in the packaging process, we select a random sample of 100 boxes to see if the machine is (on average) filling the boxes as labeled.

On Tuesday morning, at 7:45 a.m., a random sample of 100 boxes produced an average amount of 23.5 ounces.

Which of the following is an appropriate statement of the null hypothesis?
