The makers of Mini-Oats cereal have an automated packaging machine that is set to fill boxes with 24 ounces of cereal. At various times in the packaging process, we select a random sample of 100 boxes to see whether or not the machine is filling the boxes with an average of 24 ounces of cereal. Which of the following is a statement of the null hypothesis?

H' : u = 24

Step-by-step explanation: Let H' represents the null hypothesis and H1 represents the alternative hypothesis.

From the question, the initial claim or assertion is that the machine is set to fill 24 ounces of cereal.

Hence H' : u = 24 ounces This is the null hypothesis.

After taking a sample of 100 boxes, they checked whether or not the machine is filling the boxes worn an average of 24 ounces of cereal.

This is the alternative hypothesis and is written as

H1: u ≠ 24 ( 2 tailed test)
