A sample of 55 chewable vitamin tablets have a sample mean of 249 milligrams of vitamin C. Nutritionists want to perform a hypothesis test to determine how strong the evidence is that the mean mass of vitamin C per tablet differs from 248 milligrams. State the appropriate null and alternate hypotheses.

Step-by-step explanation:

The null hypothesis is mostly of the time the default hypothesis while the alternative hypothesis is the opposite of the null hypothesis and always tested against the null.

In this case study, the null hypothesis is: mean mass of vitamin c tab = to 248 milligrams

The alternative hypothesis is: mean mass of vitamin c tab =/ 248 milligrams

the correct answer is x/3+10≥32

hope this !
