Dorris, an 85-year old woman, came to your clinic complaining of left-sided calf pain. Her lower leg is swollen, red, and tender to the touch. You suspect a DVT could be the culprit and need to explain the risks a developing a PE. How would you explain a PE to Dorris and what signs/symptoms should she look for that might indicate a PE?

A manufacturer of a margarine spread containing phytosterols
claims that a person’s cholesterol can be lowered by 10% using this
product for 3 months. Does the use of this margarine (with 2g of
phytosterols to a 500g tub) for 3 months reduce the LDL-cholesterol
level in the blood of healthy adults?
a) Design an experiment to answer this question. Comment on
elements of control, randomisation and replication in your design.
Your answer should include a flow-chart schematic with full
annotations.
b) State what type of data summary statistics you would measure in
your planned study.
c) State what type of inferential analysis you would apply to make
a decision about the manufacturer’s claim. (No actual analysis is
done … no data given.)

Researchers interested in the trees of a forest in Vermont selected a random sample of 8 red oak trees and measured various characteristics of these trees. Here are the heights of the trees, in feet: 32, 48, 35, 51, 46, 30, 28, 39 In a study done several years earlier the average height of red oak trees in this forest was reported to be 35 feet. The researchers claim that the average height is now greater than 35 feet. Test the researchers claim by performing a StatKey randomization test using the sample data. What is the P-value of the test?

4. Here is a fact about permutations: (**) nPk = n!/(n-k)!, for all k € ≤ n. Let’s prove this via mathematical induction for the fixed case k=3.
(i) Write clearly the statement (**) we wish to prove. Be sure your statement includes the phrase “for all n” .
(ii) State explicitly the assumption in (**) we will thus automatically make about k=2.
(iii) Now recall that to prove by induction means to show that If mPk = m!/(m-k)! is true for all € k ≤ m then m+1Pk = (m+1)!/((m+1)-k )! for all € k ≤ m +1 must also be true. State what we must prove in the case k=3. Include the relevant statement about k=2 here, as you will need to use it in (iv).
(iv) OK so now prove (**) for the case k=3.
(a) Verify the theorem is true for the “base case” n=3 (I.E) that (**) is true for k=0,1,2,3 when n=3. You can do these four verifications by elementary means. Just remember what we mean by permutations, and thus convince us these four statements are true.
(b) Now use your cleverness to prove the underlined statement (iii) is true.
(c) Now state the fact that you have proven (**) to be true for k=3 and all n.

A candy company says that the colors of its candies are 15% yellow, 14% red, 19% orange, 25% blue, 15% green and 12% brown. In a randomly selected bag of the candies, there were 26 yellow, 24 red, 11 orange, 10 blue, 10 green, 20 brown. Is this sample consistent with the company's advertised proportions? Test an appropriate hypothesis and state your conclusion. Complete parts a through g below. Fill in blanks
a) If the company's candies are packaged in the advertised proportions, how many of each color should have been expected in the bag of candies?
|
(blank) Yellow |
(blank) Red |
(blank) Orange |
(blank) Blue |
(blank) Green |
(blank) Brown |
(Type integers or decimals rounded to two decimal places as needed.)
b) To see if the bag was unusual, should the test be for goodness-of-fit, homogeneity, or independence?
Choose the correct answer below.
A. Goodness-of-fit
B. Homogeneity
C. Independence
c) State the hypothesis
d) Check the conditions.
Select all assumptions and conditions below that are satisfied by the data.
A. Expected cell frequency condition
B. Counted data condition
C. Independence assumption
D. Randomization condition
e) How many degrees of freedom are there?
There are (blank) degrees of freedom. (Simplify your answer.)
f) Find chi squaredχ2 and the P-value.
chi squaredχ2 =
(Round to four decimal places as needed.)
P=
(Round to four decimal places as needed.)
g) State a conclusion. Assume that 0.05 is a reasonable significance level.
(blank) the hypothesis. There is (blank) evidence that the distribution of colors is not the distribution specified by the company.

Katie Smith is a 29 yr. old female, mother of two children, with a history of IV drug use. She lives in a small town in Southeast Alaska. She’s recently travelled to Anchorage for medical care after experiencing extreme exhaustion and flu-like symptoms. Her medical team here has diagnosed her with endocarditis, a kind of infection of the heart, meaning that she will need heart valve replacement surgery. Unfortunately, this would be her second valve replacement in two years, and in addition, she currently tests positive for heroin and trace amounts of opioid pharmaceuticals. Her medical team is furious. Endocarditis is a direct result of her heroin use. After her first valve replacement, her medical warned her that a return to drugs could easily kill her and that they would likely be unwilling to do another valve replacement if her drug use continued. They recommended addiction services in Anchorage to her at the time.
Now, her medical team argues that they will not perform her heart valve replacement surgery. Doing so, they believe, would be providing futile treatment and an unethical use of resources.
In answering the questions below, you may consult an essay from the Seattle Times on this kind of case: “Facing Addicts with Ruined Hearts, Many Doctors Confront Tough Ethical Questions”, from April 2018. This is a shorter version of a longer New York Times article. I will post a link to the article on Blackboard with this test.
