Chapter 3.4, Problem 181E
Sickle Cell Disease. A study published by E. Anionwu et al. in the British Medical Journal (Vol. 282, pp. 283–286) examined the steady-state hemoglobin levels of patients with three different types of sickle cell disease: HB SC, HB SS, and HB ST. Use the following boxplots to compare the hemoglobin levels for the three groups of patients, paying special attention to center and variation.

Suppose a study investigated the effects of vitamin A, vitamin C, and omega-3 fatty
acids supplements on improving eye health and vision. 300 adults volunteered to take
part in the study. In the study, participants were randomly assigned to one of 3
different levels of Vitamin A (Level A, Level B, or Level C) and randomly assigned to one
of 2 different levels of Vitamin C (Level 1 or Level 2) and randomly assigned to one of 2
different levels of omega-3 fatty acid (Level I or Level II).
a. Identify the subjects of the study.
b. Identify the factor(s) for the study and the number of treatment level(s) for each
factor.
c. How many different treatment groups are there in this study?
One variety of corn is genetically modified to produce chemicals for defense against predators. The standard corn contains the same standard genotype, but without genetic modification for the chemicals. The two types of corn are then planted in randomly placed adjacent plots across a single field. The amount of predators that are present when the corn has matured are then recorded. The data that was recorded of the predators present among each type are listed.
Has genetic alterations decreased the amount of predators for the altered genotype? Normality tests for the populations of both contain a p value less than 0.05. The given alpha is 0.05
Modified Corn (20, 18, 26, 23, 17, 23, 22)
Standard Corn (89, 64, 102, 96, 56, 77, 84, 59)

The Lion’sMane. In a study by P. M.West titled “The Lion’s Mane” (American Scientist, Vol. 93, No. 3, pp. 226–236), the effects of the mane of a male lion as a signal of quality to mates and rivals was explored. Four life-sized dummies of male lions provided a tool for testing female response to the unfamiliar lions whose manes varied by length (long or short) and color (blonde or dark). The female lions were observed to see whether they approached each of the four life-sized dummies.

- Captivity can influence immunological responses in some mammals. Seeber et al. (2020) investigated various aspects of immunological responses in captive and free-ranging zebras. One aspect of the study involved samples of 12 free-ranging zebras from Namibia, 9 from Tanzania, and 38 captive zebras from various zoos in Europe. (All of these were non-lactating females.) One of the measured variables from blood samples was lysozyme concentration (μg/L). (Lysozyme is a biomarker of the immune response.) The researchers were interested in investigating possible differences in lysozyme concentration between zebras in the various locations. As part of the analysis, they carried out a one-way ANOVA on the lysozyme concentrations for the zebras from the 3 locations, and found the following output.

This makes logical sense since BMI is a function of weight. How to decide which of the variables to retain for constructing the regression model?

- A study is designed to test the effect of light level on exam performance of high school students. The researcher believes that light levels might have different effects depending on a person's grade in school (1st year, sophomore, junior, or senior), so wants to make sure all grades are equally represented in each treatment. The treatments are fluorescent overhead lighting, yellow overhead lighting, no overhead lighting (only desk lamps).

The results were tabulated in a two-way table in which the column variables were the vitamin supplements and the row variables were the cold responses.
