A gardener wants to try different combinations of fertilizer (none, 1cup, 2cups) and mulch (none, wood chips, pine needles, plastic) to determine which combination produces the highest yield for a variety of green beans. He has 60green-bean plants to use in the experiment. If he wants an equal number of plants to be assigned to each treatment, how many plants will be assigned to each treatment?

a. 1

groups. The treatment group would be offered hearing aids, dentures, transportation, and other services not available without charge to the control group. The review board believed that providing these services to some but not other people in the same institution raised ethical questions. Do you agree?

A louse-y situation A study published in the New England Journal of Medicine compared two medicines to treat head lice: an oral medication called ivermectin and a topical lotion containing malathion. Researchers studied 812 people in 376 households in seven areas around the world. Of the 185 households randomly assigned to ivermectin, 171 were free from head lice after 2 weeks, compared with only 151 of the 191 households randomly assigned to malathion.

a. Calculate the difference (Ivermectin 鈥� Malathion) in the proportion of households that were free from head lice in the two groups.

One hundred trials of a simulation were performed to see what differences in proportions would occur due only to chance variation in the random assignment, assuming that the type of medication doesn鈥檛 matter. The results are shown in the dotplot.

b. There is one dot at 0.09. Explain what this dot means in this context.

c. Use the results of the simulation to determine if the difference in proportions from part (a) is statistically significant. Explain your reasoning.

Can a vegetarian or low-salt diet reduce blood pressure? Men with high blood pressure are

assigned at random to one of four diets: (1) normal diet with unrestricted salt; (2)

vegetarian with unrestricted salt; (3) normal with restricted salt; and (4) vegetarian with

restricted salt. This experiment has

  1. one factor, the type of diet.
  2. two factors, high blood pressure and type of diet.
  3. two factors, normal/vegetarian diet and unrestricted/restricted salt.
  4. three factors, men, high blood pressure, and type of diet.
  5. four factors, the four diets being compared.

Sampling gravestones The local genealogical society in Coles County, Illinois, has compiled records on all 55,194gravestones in cemeteries in the county for the years 1825to 1985. Historians plan to use these records to learn about African Americans in Coles County鈥檚 history. They first choose an SRS of 395records to check their accuracy by visiting the actual gravestones.

a. Explain how you would use a random number generator to choose the SRS. Your description should be clear enough for a classmate to carry out your plan.

b. Use your method from part (a) to choose the first 3gravestones
