Answer:
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
