Question
Practice A. Complete the table. Read the given problem then solve using the steps of hypothesis
testing using population means by filling the blanks.
The owner of a factory that sells a particular bottled fruit juice claims that the average
capacity of their product is 250 ml. To test the claim, a consumer group gets a sample of 100
such bottles, calculates the capacity of each bottle, and then finds the mean capacity to be 248
ml. The standard deviation s is 5 ml. Is the claim true? Write your answer on a separate sheet of
рaper.
