Imagine you are testing for the effects of two experimental drugs (data sets B and C)relative to a control group (Data set A) on a physiological variable.
Data set A: 105.51,111.46,104.35,115.27,113.98,119.18,116.45,119.98
Data set B: 93.63,88.90,95.03,86.08,85.86,98.22,105.46,96.50
Data set C: 95.12,97.12,94.08,99.78,101.44,101.27,104.70,103.70
b) Use the Bonferroni-Holm (regardless of whether part “a” is significant or not) to examine all pairwise comparisons. Show all your calculations and state your conclusions.

A researcher is testing 4 different blood coagulation drugs. The
drugs are labeled A,B,C and D. He is interested in how the drugs
affect the blood coagulation rates of mice. The coagulation rate is
the time in seconds that it takes for a cut to stop bleeding. He
has 16 mice available for the experiment, so he will use 4 on each
drug, randomized.

A, B and C be sets.
(a) Suppose that A ⊆ B and B ⊆ C. Does this mean that A ⊆ C?
Prove your answer. Hint: to prove that A ⊆ C you must prove the
implication, “for all x, if x ∈ A then x ∈ C.”
(b) Suppose that A ∈ B and B ∈ C. Does this mean that A ∈ C?
Give an example to prove that this does NOT always happen (and
explain why...

Averages and variation
Consider two data sets A and B. The sets are identical except
the high value of the data set B is three times greater than the
high value of data set A.
(a) How does the median of the two data sets compare?
(b) How do the means of the two data sets compare?
(c) How do the standard deviations of the two data sets
compare?
(d) How do the box- and –whisker plots of the two...

Construct a 95% confidence interval for data sets A and B. Data
sets A and B are dependent. Assume that the paired data came from a
population that is normally distributed, and round your final
answer to three decimal places.
setA: 30 28 47 43 31
setB: 28 24 35 35 22
A) What is the mean of the differences( )?
B) What is the standard deviation of the differences( )?
C) What is the critical t-value( )?
D) What...

An experimental study was conducted in order to compare the
effectiveness of two drugs in the treatment of hypertension. 60
patients with similar hypertension conditions were included in the
study. Researchers randomly assigned 30 hypertensive patients to
each treatment group. The patients in group one received drug 1
while those in group two received drug 2. After the treatment, the
patients in group one had an average blood pressure of 131.80 with
a standard deviation of 2.50, and the patients...

Select two data sets and decide which hypothesis testing
discussed in class should be used and matched with your data set.
Construct a 99% confidence interval for a mean difference and Test
at a 1% significance level. Use both the P-value and the
critical-value approaches to make this test and interpret your
results. If you cannot reject the null hypothesis, please adjust to
5% or 10% significance level.

Given two sets of data, A and B.
i) Data set A has an r value of -.81 and data set B has an r
value of .94 Describe the differences between the two data sets as
completely as you can using the regression information we have
learned.
ii) Which linear regression equation, the one for A or the one
for B, would probably be a better predictor? Why?
