Problem 1. A medical researcher looking at adrenal suppression by measuring post-metyrapone test ACTH values which are grouped as Low-range ( 319pg/ml). She wants to know whether it is associated with SNP genotypes/alleles (labeled as AA and AB). Data is provided in the following table:
____AA AB
Low 33 3
Mid 24 5
High 26 5
a. State your null and alternative hypotheses (2 pts)
b. Test your above hypothesis and state and support your conclusion (10 pts). Use α=0.05.
c. If the null is rejected, where the difference is mostly coming from (3 pts).

A researcher conducts an Analysis of Variance (ANOVA) test
looking at the effect of different treatment program options
(therapy, education and reentry services) and finds that drug use
levels vary significantly among between the participants in each of
these three groups. For example, the therapy group had lowest
amount of drug use (mean=2.0), the education group had the highest
(mean=7.0) and the reentry services group was in the middle
(mean=6.0). The researcher follows the steps to conduct an ANOVA
appropropriately....

A researcher is looking at the correlation between depression
and anxiety using a two-tailed test with an alpha level of .05. The
researcher finds the following correlation coefficient: r
= .22, p = .04. What can the researcher conclude?
a. There is a significant positive relationship between
depression and anxiety in this sample.
b. There is no statistically significant relationship between
depression and anxiety in this sample.
c. There is a significant negative relationship between
depression and anxiety in this...

write a hypothesis test problem. Post your problem with
a solution.
Option 1.
Think about two population means that you may be interested in
and propose a hypothesis test problem for this parameter. For
example, you may believe that the average family size in Illinois
is greater than the average family size in Wisconsin. Your data
could be that you spoke with 20 people (10 in Illinois and 10 in
Wisconsin) and found the following family sizes: 5, 6, 5,...

(Computational) Applied Statistics
Problem 1: A noted medical researcher has suggested that a heart
attack is less likely to occur among adults who actively
participate in athletics. A random sample of 300 adults is
obtained. Of that total, 100 are found to be athletically active.
Within this group, 10 suffered heart attacks; among the 200
athletically inactive adults, 26 had suffered heart
attacks.
a) Test the hypothesis that the proportion of adults who are active
and sufferedheart attacks is different...

A medical researcher suspects that giving post-surgical patients
large doses of Vitamin E will speed their recovery times by helping
their incisions heal more quickly.
Design an experiment to test this conjecture. It must be
randomized, comparative, double blind and placebo controlled.
Be sure to identify the factors, levels, treatments, response
variable and role of randomization.
Thank you.

A medical researcher believes that a drug changes the body's
temperature. Seven test subjects are randomly selected and the body
temperature of each is measured. The subjects are then given the
drug, and after 30 minutes, the body temperature of each is
measured again. The results are listed in the table below. Is there
enough evidence to conclude that the drug changes the body's
temperature? Let d=(body temperature after taking drug)−(body
temperature before taking drug) d=(body temperature after taking
drug)−(body...
