The null hypothesis ($H_0$) is usually that the machine is filling boxes with the correct average amount (24 ounces in this case). The alternative hypothesis ($H_a$) is the opposite of the null hypothesis. It represents the claim we are trying to find evidence for. Here, it's that the machine is not filling the boxes with an average of 24 ounces.
