Step-by-step explanation:

The null hypothesis is that the mean vitamin C, μ is equal to the sample mean μ₀

The alternative hypothesis is that the mean vitamin C, μ is not equal to the sample mean μ₀

Step-by-step explanation:

The number chewable vitamin tablets in the sample, n = 85

The mean amount of vitamin C, μ₀ = 272 milligrams

The hypothesis test is to determine the strength of the evidence that the mean mass of vitamin C per tablet differs from 270 milligrams

The null hypothesis, H₀:  μ = μ₀ =272 milligrams

The alternative hypothesis, Hₐ: μ ≠ μ₀ = 272 milligrams
