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.

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

An experiment to test the effectiveness of regular treatments with fluoride varnish to reduce tooth decay involved 36 volunteers who had half of their teeth (the right side or left side, determined by a coin flip) painted with a fluoride varnish every six month for 5 years. At the end of the treatments, the number of new cavities during the treatment period was compared on treatment (fluoride varnish) side versus the control (no fluoride varnish) side. The appropriate statistical test for analyzing the results of this experiment is

After some discussion Kelly and Roberto decide to scrap their original designs and
make just one garden instead. They plan to place the twoxftbyxftsquare plots side
by side and then make a rectangular gravel border around the resulting it by 25t
plot. The area of the new garden and border will equal the sum of the areas of the two
original gardens and borders.
Task Description
Write expressions for the length and width of the plot consisting of the new garden
and its gravel border. Each expression must be a linear polynomial with integer
coefficients. Use your expressions to draw a sketch of the new garden and border.
