Question 2

A researcher wants to investigate if there is a relationship between the blood pressure level and the type of diabetes of diabetic patients. He selects 60 diabetic patients at random and classifies them according to their blood pressure level and type of diabetes.

Low Blood Pressure

Normal Blood Pressure

High Blood Pressure

Type I Diabetes

14

18

8

Type II Diabetes

5

6

9

For this data,

  1. What is the appropriate test for this information (ANOVA, goodness-of-fit, test of independence or test of homogeneity)? Explain briefly. [2]
  2. What is the distribution of the test statistic? How many degrees of freedom does it have?[2]
  3. Write down the hypotheses being tested by the test statistic. [2]
  4. Find the critical value(s) for this test, using a significance level of . [1]
  5. What do you conclude from this test? [2]

A researcher wants to investigate a connection between systolic blood pressure and body type to see if those with different body types had different systolic blood pressures on average. Body type is a categorical variable with levels 0 = Normal, 1 = Overweight, and 2 = Obese. Why should the researcher not use two-sample t-tests to see what the differences are between the means of these three groups?

A medical researcher wants to examine the relationship of the blood pressure of patients before and after a procedure. She takes a sample of 27 people and measures their blood pressure before undergoing the procedure. Afterwards, she takes the same sample of people and measures their blood pressure again. The researcher wants to test if the blood pressure measurements after the procedure are less than the blood pressure measurements before the procedure and, thus, the hypotheses are as follows: Null...

A researcher wishes to investigate the idea that eating salt raises blood pressure. She randomly selects two groups, one with 15 people and one with 13 people. She arranges that Group 1 (15 people) will be on a high sodium diet for 2 weeks, while Group 2 will be on a low sodium diet. She measures their blood pressure after the two weeks. The mean systolic blood pressure for Group 1 is found to be 120 with a sample standard...

A medical researcher is investigating the effect of drinking coffee on systolic blood pressure. The researcher assumes the average systolic blood pressure is 120 mmHg. For a random sample of 200 patients, the researcher takes two measurements of systolic blood pressure. The first systolic blood pressure measurement is taken during a week when the patients drink no coffee, and the second systolic blood pressure measurement is taken during a week when the patients drink at least two cups of coffee....
