Problem
A manufacturer claims its snack crackers have an average of no more than $120 \mathrm{mg}$ of sodium. State the null and alternate hypotheses.
Solution
Step 1 ：State the null and alternate hypotheses for the average sodium content of the snack crackers.
Step 2 ：The null hypothesis is that the average sodium content of the snack crackers is equal to \(120 \mathrm{mg}\).
Step 3 ：The alternative hypothesis is that the average sodium content of the snack crackers is more than \(120 \mathrm{mg}\).
Step 4 ：Final Answer: The null hypothesis is that the average sodium content of the snack crackers is equal to \(\boxed{120 \mathrm{mg}}\), and the alternative hypothesis is that the average sodium content of the snack crackers is more than \(\boxed{120 \mathrm{mg}}\).
