Chapter 11, Problem 57CRE
Triglycerides and Gender Using the NHANES data, we performed an ANOVA to test whether gender is associated with level of triglycerides, a form of fat, in the blood. ANOVA and t-test output from a two-sample t-test is shown. In both cases, we are testing the hypothesis that the mean triglyceride levels for men and women are different. Assume that conditions for both tests have been met.
Compare the output by comparing p-values. Square the t-value to see what you get for comparison. Explain.

A doctor in Cleveland wants to know whether the average life span for heart disease patients at four
hospitals in the city differ. The data below represents the life span, in years, of heart disease
patients from each hospital. Perform an ANOVA test with a 9% level of significance to test whether
the average life span of heart disease patients in Cleveland differs depending on the hospital that
treats them
Life Span of Patients Treated at Hospital 1:
7.4, 7.8, 7.7, 7.5, 8, 8.2, 7.8, 8.6, 8, 7.8, 8.3, 8.3, 8, 7.6, 8.2, 7.9, 7.3, 8, 8.6, 7.3, 8.3, 8, 7.8, 8, 7.8, 8.1,

- Factor V is a protein involved in the forming of blood clots. The higher the level of factor V, the faster the blood clots. A Blood Transfusions Service is interested in the effects of sterilization of blood plasma because factor V is unstable and may break down during sterilization. The table below gives measured levels of factor V in blood samples from nine donors. Both pre- and post-sterilization measurements are given for each person. Test whether the mean factor V levels are different post-sterilization. Run the test at a 5% level of significance. Give each of the following 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value.

Subjects were sampled based on their clinical change to treatment and then asked whether they had a high or low degree of infiltration. The degree of infiltration measures a type of skin damage. We will use clinical change response scores {-1, 0, 1, 2, 3}. The question of interest is whether degree of infiltration is associated with clinical change. (a) Compute the sample proportions of having a high degree of infiltration for each clinical change group? What type of variable is Clinical Change? (B)Conduct a Cochran-Armitage trend test at the 5% significance level to determine whether there is an association between degree of infiltration and clinical change. (C)Now, ignore the fact that clinical change is an ordinal variable.
