1. Your boastful roommate claims that fans for the Chicago Bears (the city’s football team) are simply more intelligent than the average person. With your newly-developed statistical tools, you decide to put this hypothesis to the test. You know that the standard intelligence quotient (IQ) score has a population mean of 100 with a standard deviation of 15. You find that a random sample of 121 Bears fans has an average IQ score of 103. Use this evidence to test your roommate’s argument that Bears fans are more intelligent than the general population.

A business needs to know whether customers of different genders have specific favourite colours. Using the following information, develop a contingency table test. Male: 10 blue, 18 red, 22 black Female: 25 blue, 11 red, 14 black At at 0.05 level of significance, use formal hypothesis test to determine whether colour preference of a customer depends on gender.

You and your best friend have just finished a Marketing Degree and are thinking about starting a company that targets virtual advertising for the likes of Facebook, Instagram and Tic Tock. The business will be run from your study as the cost of commercial leasing is too expensive for now, but you need state of the art equipment to compete in the field.

(Q001) Glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency) is an inherited disorder where either the body has less of the G6PD enzyme than normal or the available G6PD is not functioning correctly. This deficiency affects red blood cell function and may result in anemia (the destruction of red blood cells) when people with the condition have infections, are taking certain medications, or eat certain foods. People with G6PD deficiency may have some protection from malaria because their abnormal red blood cells interfere with the reproduction of the malaria parasite in their bodies.

Consider the prevalence of G6PD deficiency estimated by the World Health Organization (WHO) as shown in the map on p. 247 of your lab manual. Compare the distribution of G6PD deficiency with the distributions of the sickle-cell trait and malaria shown in Figure 8.9 on p. 238 of your lab manual. What similarities between these distributions do you notice? What differences do you notice?

(Q002) Why might these similarities and differences exist? Be sure to consider the evolutionary context (including the natural environment, cultural practices, and interbreeding).

1. Explain what a process is and how activities in a process function as a system. Find an example of a process, and identify the different activities involved. How would you improve this process? What would that involve?

In a study of red/green color blindness, 850 men and 2250 women are randomly selected and tested. Among the men, 80 have red/green color blindness. Among the women, 7 have red/green color blindness. Test the claim that men have a higher rate of red/green color blindness.

1. The test statistic is:

2. The p-value is :

3. Is there sufficient evidence to support the claim that men have a higher rate of red/green color blindness than women using the 0.01% significance level? Y or N

4. Construct the 99% confidence interval for the difference between the color blindness rates of men and women.

(_______ <(p1−p2)< ______)

5. Which of the following is the correct interpretation for your answer in part 2?

A. We can be 99% confident that the difference between the rates of red/green color blindness for men and women lies in the interval

B. We can be 99% confident that that the difference between the rates of red/green color blindness for men and women in the sample lies in the interval

C. There is a 99% chance that that the difference between the rates of red/green color blindness for men and women lies in the interval

D. None of the above

Sarah, a 45-year-old female presents to the outpatient office complaining of red, “itching, burning, gooey” eyes. She reports noticing discomfort three days ago after returning from a weekend vacation to a waterpark. Sarah reports trying to rinse her eyes out with contact lens solution several times yesterday, but feels this is not helping. She denies any fever or chills. She has a past history of seasonal allergies, and occasionally takes Zyrtec PRN for nasal congestion. Her last dose was yesterday. Sarah works as a teacher in a daycare center during the day, and cleans office buildings at night. She is single, and is sexually active with 3 partners in the past 6 months. She smokes ½ pack per day and takes a daily multivitamin.

Her Snellen Eye check is 20/20 with contact lenses. T98.2, BP 92/60, HR 64, RR 20

1. Highlight the pertinent information in the above case study. Use those details to form a 1-2 sentence problem statement using medical terminology and your knowledge of syndromes.

2. Highlight one of the following frameworks that you will use in creating your differential diagnoses list:

ANATOMIC     PHYSIOLOGIC      MNEUMONIC (vindicate)

Brainstorm the Differential Diagnoses List:

List the “key” pertinent positives and/or negatives for each diagnosis

3. Choose 5-8 of the most likely differential diagnoses and list them in order from most likely (your “working diagnosis”) to least likely. Identify your “must not miss”/” potentially deadly” diagnoses in bold.

Use your working diagnosis to answer the following questions:

1: Are there any risk factors that predisposed this patient to the working diagnosis?

2: Consider Past Medical history, Social and/or Family history- does any of this influence or support your working diagnosis? if so, explain.

2: What is the classic subjective presentation for a client who has your working diagnosis? (HPI-OLDCART-PQRST)

4: List the body systems will you need to examine based on your working diagnosis, and include the findings that would be expected in that condition.

5: What procedures, labs or diagnostic studies will you need to order to support your working diagnosis, and indicate what results would support your diagnosis.

6: Using approved guidelines from your guideline texts (Fenstermacher or Cash & Glass), establish the treatment plan for this patient. Be specific and include medications you would order, strength, frequency, length of treatment and any referrals for interprofessional care.

7: What type of education will the patient require about the diagnosis and management plan?

8: What is your follow up plan for the patient?
