Homework Answers
Given:
n = 330
= 75
S = 11
Therefore,
Standard error (SE) =
ANSWER: E
E. 0.606
Question 12.
n = 13
= 0.01

S-adenosyl methionine (SAM-e) is a naturally occurring compound in human cells that is thought to have an effect on depression symptoms. Suppose that a researcher is interested in testing SAM-e on patients who are struggling with HIV. He obtains a sample of n = 20 patients and asks each person to take the suggested dosage each day for 4 weeks. At the end of the 4-week period, each individual takes the Beck Depression Inventory (BDI), which is a 21-item, multiple-choice...

please help with question 4
degrees of freedom for either the numerator or denominator of F, use the closest smaller number. For instance, if the degrees of freedom for the denominator were df, 23 you would use the critical value for df = 20 (2,3) 4. Chapter 10, Problem 10.10 If the degrees of freedom for I do not appear in Table A.2 use the closest smaller degrees of freedom to determine the critical value of t. For instance, if...
