Textbook Question
Chapter 10, Problem 24PS
Multiple myeloma, or blood plasma cancer, is characterized by increased blood vessel formulation (angiogenesis) in the bone marrow that is a predictive factor in survival. One treatment approach used for multiple myeloma is stem cell transplantation with the patient’s own stem cells. The data stored in Myeloma, and shown on page 369 represent the bone marrow microvessel density for patients who had a complete response to the stem cell transplant (as measured by blood and urine tests). The measurements were taken immediately prior to the stem cell transplant end at the time the complete response was determined.
a. At the 0.05 level of significance, is there evidence that the
b. Interpret the meaning of the p-value in (a).
c. Construct and interpret a
d. What assumption is necessary in order to perform the test in (a)?

A medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y) Generally, the systolic blood pressure
depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the
age of the person constant. For her study, she collects a random sample of 125 patients from the city and estimates the following regression function:
Y= 15.50 + 0..90B+1.15A.
(0.55)
(0 40)
The test statistic of the study the student wants to conduct (Ho: B, = 0 vs. H, B, #0), keeping other variables constant is.
(Round your answer to two decimal places.)
At the 5% significance level, the student will
▼ the null hypothesis.
Keeping BMIl constant, she now wants to test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure.
So, the test statistic associated with the one-sided test the…
Anemia (low healthy blood cells or hemoglobin) has an important role in exercise performance.
However, the direct link between rapid changes of hemoglobin and exercise performance is
still unknown. A study investigated 18 patients with a blood disorder (beta-thalassemia).
Participants in the study performed an exercise test before and the day after receiving a blood
transfusion. Data are given in the table.
