A sample of 85 chewable vitamin tablets have a sample mean of 272 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 270 milligrams.
State the appropriate null and alternative hypotheses.

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

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

207/8 is the right
