Question: You are a seller of heirloom garden seeds. You have several machines that automatically load the seeds into packages. One of your machines is suspected of sometimes being inaccurate and of underloading or overloading the packages. You take a random sample of 20 packages and record their weights as follows: 3.09, 2.74, 2.49, 2.99, 3.22, 2.51, 2.28, 3.54, 2.52, 3.20, 3.09, 2.56, 3.43, 3.25, 2.69, 2.49, 3.30, 2.69, 2.89, and 3.57. In the past, it has been determined that the average weight should be 2.88 ounces. Write the null and research hypotheses and select the correct statistical test to determine if your sample evidence indicates that the machine is malfunctioning.
