Q.Explain the flaws in the following analysis or conclusion. (Note that this is not about chi-squared test per se, perhaps, it is about what a statistical analysis (hypothesis testing in this case) can tell us and what it cannot) Background - The Scholarship Committee comprises 3 faculty members, one of whom is Professor X. Professor X also wrote recommendation letter for 5 students who took his class earlier and four of them were awarded scholarships (out of a total of six scholarships awarded to graduate students). A student who applied but was not awarded a scholarship accused Professor X of favoritism, claiming that he/she was denied a scholarship despite having a very high GPA because he/she did not take class under Professor X and had declined him/her a recommendation letter. The student then did following statistical analysis as an evidence of favoritism . The student runs a Chisq-test and his result shows not independent between students who took class under Professor X and Students got scholarship. H0: students who get scholarship is independent with whether they have taken class under Professor X H1: not independent # Let total number of students who applied for scholarship is 70, and only 5 people get the scholarship, conservatively estimate only 3 out of 5 students took Class with ProfessorX, the other two selected did not take Class with ProfessorX # chisquare test shows the p-value <0.05, thus we reject H0 at .05 level and conclude students who got scholarship was affected by whether they have class under Professor X #student in addition tests , how about the total applicants were 60, or 80? and find out either case we reject H0, they are not independent.

Racism, juries, and interactions: In a study of racism, Nail, Harton, and Decker (2003) had participants read a scenario in which a police officer assaulted a motorist. Half the participants read about an African American officer who assaulted a European American motorist, and half read about a European American officer who assaulted an African American motorist. Participants were categorized based on political orientation: liberal, moderate, or conservative. Participants were told that the officer was acquitted of assault charges in state court but was found guilty of violating the motorist’s rights in federal court. Double jeopardy occurs when an individual is tried twice for the same crime. Participants were asked to rate, on a scale of 1–7, the degree to which the officer had been placed in double jeopardy by the second trial. The researchers reported the interaction as F(2, 58) = 10.93, p < 0.0001. The means for the liberal participants were 3.18 for those who read about the African American officer and 1.91 for those who read about the European American officer. The means for the moderate participants were 3.50 for those who read about the African American officer and 3.33 for those who read about the European American officer. The means for the conservative participants were 1.25 for those who read about the African American officer and 4.62 for those who read about the European American officer. ***This prompt requires certain formatting so that you can draw tables and bar graphs. You can use Microsoft Excel or Microsoft Word, or any other word processing software to create your post/ post it as an attachment in the discussion. Draw a table of cell means that includes the actual means for this study. Do the reported statistics indicate that there is a significant interaction? If yes, describe the interaction in your own words. Draw a bar graph that depicts the interaction. Include lines that connect the tops of the bars and show the pattern of the interaction. Is this a quantitative or qualitative interaction? Explain. Change the cell mean for the conservative participants who read about an African American officer so that this is now a quantitative interaction. Draw a bar graph that depicts the pattern that includes the new cell means. Change the cell means for the moderate and conservative participants who read about an African American officer so that there is now no interaction. Draw a bar graph that depicts the pattern that includes the new cell mean

Question 1 - Create a class named Student that has fields for an ID number, number of credit hours earned, and number of points earned. (For example, many schools compute grade point averages based on a scale of 4, so a three-credit-hour class in which a student earns an A is worth 12 points.) Include methods to assign values to all fields. A Student also has a field for grade point average. Include a method to compute the grade point average field by dividing points by credit hours earned. Write methods to display the values in each Student field. Save this class as Student.java.

5.Jack needs $6100 in 6 years from today to buy a holiday. He invests $2500 today. Find the effective annual rate of interest that Jack needs to earn on this amount (as a %, 2 decimal places) in order to reach his goal.
(Solve using excel =RATE function; Answer in percentage to two decimals without the % sign e.g. 1.88

10.You have the alternative of paying for university fees today for a payment of $15,000 or, you can select a payment plan where you pay $8,000 in 6 months from today and another $12,000 in exactly 18 months from today. If the interest rate is 9.9%p.a. compounding monthly, what is the advantage that the payment plan has over the upfront payment?

Assume there are three companies that in the past year paid exactly the same annual dividend of $1.77 a share. In​ addition, the future annual rate of growth in dividends for each of the three companies has been estimated as​ follows:

Buggies-Are-Us: g = 0 (i.e., dividends are expected to remain at $1.77/share)

Steady Freddie, Inc: g = 7% (for the foreseeable future)

Gang Buster Group:

Assume also that as the result of a strange set of​ circumstances, these three companies all have the same required rate of return ​(r = 11%).

(for all answers round to the nearest cent)

a. For​ Buggies-Are-Us, the value of the​ company's common shares is $_____.

For Steady​ Freddie, Inc., the value of the​ company's common shares is $_____.

For Gang Buster Group, the value of the company's common shares is $_____.

b. Comment briefly on the comparative values of these three companies. What is the major cause of the differences among these three​ valuations?

A. The value of​ Buggies-Are-Us is ​$16.09​, compared to ​$47.25 for Steady​ Freddie, Inc., and ​$57.22 for Gang Busters Group. The difference in values is caused by the difference in dividend growth rates. The​ Buggies-Are-Us dividends do not​ grow, resulting in the lowest value. The dividends of Steady​ Freddie, Inc., grow at a constant rate of 7% forever, whereas Gang Busters​ Group's dividends grow at approximately​ 12% for the first four years and 11% from year five to the foreseeable future. The higher growth in dividends in the earlier years causes the stock of Gang Busters Group to be worth more than Steady​ Freddie, Inc., stock.

Kim is a 27-year-old woman who recently moved from a small

town in Texas to work in the city of Dallas as a reporter for one

of the major newspapers. She is 5’6” tall and weighs 115 lb. To

keep in shape she likes to jog, which she did regularly in her

hometown. She doesn’t know anyone in Dallas and has been

lonely for her family since arriving. But she has moved into a

small apartment in a quiet neighborhood and hopes to meet

young people soon though her work and church.

On the first Saturday morning after she moved into her new

apartment, Kim decided to get up early and go jogging. It was

still dark out, but Kim was not afraid. She had been jogging

alone in the dark many times in her hometown. She donned her

jogging clothes and headed down the quiet street toward a nearby

park. As she entered the park, an individual came out from a

dense clump of bushes, put a knife to her throat, and ordered her

to the ground. She was raped and beaten unconscious. She

remained in that condition until sunrise when she was found by

another jogger who called emergency services, and Kim was

taken to the nearest emergency department. Upon regaining

consciousness, Kim was hysterical, but a sexual assault nurse

examiner (SANE) was called to the scene, and Kim was assigned

to a quiet area of the hospital, where the post-rape examination

was initiated.

Answer the following questions related to Kim:

1. What are the initial nursing interventions for Kim?

2. What treatments must the nurse ensure that Kim is aware

are available for her?

3. What nursing diagnosis would the nurse expect to focus on

with Kim in follow-up care?
