In SUMMER 2018 session, Sonia Buchanan, took four final exams. The exam mean and standarddeviation for each course (class) along with Sonia’s score on each exam are listed in table below.Assume that the grades on each exam are NORMALLY DISTRIBUTED.

1. Discuss the importance of the normal distribution curve in the Behavioural Sciences

2. With respect to the normal curve what is a percentile rank? Give an example using a diagram

3. Calculate Sonia's percentile rank for the Life and Teachings of Christ

4. On which exam did Sonia do best relative to the other students in the class

In an effort to get a better understanding of the factors affecting a high school student choice of college selection, 600 students were reported to apply for college admission from Sacramento county and they were asked to provide information on SAT scores and parent’s income. Portion of that data is reported in the table below. Use Chi-square test to examine how the categorical variable parent’s income affects the choice of professional degree among those who have applied for admission. Run the Chi square test and answer the three parts.

1. Write the null and alternative hypothesis
2. Determine the P value and provide its interpretation
3. What is your conclusion after running the Chi square test?

Describe the similarities and differences between

A.    A prospective cohort study and a retrospective cohort study

B.    A prospective cohort study and a case control study

C    A case control study and retrospective cohort study

D.    Is a case control study always retrospective? Why or why not?

Which option below best represents the main difference between cohort studies and clinical trials?

a. The investigator and other study staff are blinded in a cohort study but not in a clinical trial

b. Cohort studies are conducted with humans and clinical trials are conducted with animals

c. Study investigators control the participant’s exposure in clinical trial, but not in a cohort study

d. Study investigators follow up participants over time in clinical trials, but not in cohort studies

1) Determine the potential at a point 35 cm from;

a) a +15 x10-6C charge point    b) at a 12 uC charge point

2) Determine the minimum work to be done by an external force that has a charge q = 300 uC from a distance (not defined) to a point 50 cm with a load of 20 x 10-6 C.

3) We have 2 charging points, where Q1 = -25.0 uC and the other has Q2 = +50.0 uC are separated by 12 cm (see image). If the electric field at point P is zero (0).

Determine the distance at which we can find Q1 from point P. Note: u = micro

Is the SAT Really the Problem? Family breakdown causes serious disadvantages when it comes to college. By William McGurn May 25, 2020 12:32 pm ET When the University of California announced it will stop using the SAT and ACT for admissions, it sent tremors through the world of higher education. If only because of its sheer size—the UC system covers 285,000 students over several campuses—others are bound to follow. Thursday’s decision by the Board of Regents was taken, as are so many decisions in academia these days, in the name of equity and diversity. Requiring SAT scores, the argument goes, discriminates against low-income, black and Latino children who perform poorly on the tests because they lack advantages such as prep courses. To amp up the pressure, a coalition of students and activist groups filed suit in November against the Board of Regents, challenging the SAT requirement on these grounds. Undeniably wealth is a big advantage. But if the idea is to address what’s keeping children from a college degree, instead of papering over the achievement gap, it might be better to address the elephant in the room: family. It’s taboo to raise it, but for all the invocations of “science” and “data-driven decisions,” seldom is any recognition given to what the data tell us about the most privileged kids of all: those living with their biological parents under the same roof. “Family structure is about as important as family income in predicting who graduates from college today,” says W. Bradford Wilcox, a visiting scholar at the American Enterprise Institute, professor of sociology at the University of Virginia and a senior fellow at the Institute for Family Studies. “In the absence of SAT scores, which can pinpoint kids from difficult family backgrounds with great academic potential, family stability is likely to loom even larger in determining who makes it past the college finish line in California.” The data are pretty conclusive. The more intact the family, the better the education outcomes. In a new IFS study (Links to an external site.) released Monday, research psychologist Nicholas Zill reports that when it comes to graduation from top colleges, “students from intact families are twice as likely to do so as those from all other family types combined.” By dropping SATs, UC hopes to produce a student body that includes higher percentages of blacks and Latinos. This requires discrediting the SATs as an indicator of college performance (a point contested by the UC Academic Senate). It also requires finding a way to make room for the students it wants by reducing the number of Asian-Americans (13.6% of California’s population but 29.5% of UC undergraduates). This is why the Asian American Coalition for Education warned the regents that, without the SAT, Asian-American applicants will “become easy victims of various radical acts of racial balancing.” Wenyuan Wu, who addressed the regents on the coalition’s behalf, tells me she cringes whenever the anti-SAT crowd invokes the “racial/socioeconomic biases argument.” She asks: “What about those Chinatown kids whose parents toil in ethnic enclaves with low incomes and tremendous language barriers?” Which raises a further indelicate question: Is it a coincidence that Asian-Americans, who disproportionately earn entry into UC, disproportionately come from intact families? If it’s unjust that rich kids get test prep from their parents, why doesn’t the university simply come up with a good prep course and provide it free to anyone who wants it? If the rejoinder is that the wealthy kids enjoy the further advantage of better schools, why do so many SAT opponents also reject measures that might help level the playing field—vouchers and charter schools come to mind—by giving underserved kids the opportunity of going to a good school too? The modern American university isn’t afraid to weigh in when it comes to issues outside its direct purview. Two days before UC announced its decision on the SAT, it boasted of having completely divested from fossil fuels. But when it comes to addressing a major factor keeping students out of its system and thus widening the achievement gap—crickets. As Charles Murray noted in “Coming Apart” (2012), the data showing the advantage to children of living with their biological parents across a range of outcomes are broadly accepted by social scientists. But those data are “resolutely” ignored by “network news programs, editorial writers for the major newspapers, and politicians of both major political parties.” Not to mention the UC regents. “Given the science,” Mr. Wilcox says, “why can’t universities bring themselves to tell the truth that if you’d like your kids to get a college degree—especially from a selective college—you’d do well to get and stay married?” COMMENT

1. President Trump passed an executive bill, banning Chinese airplanes from landing in America, and Chinese Post Graduate students from studying in America. As Chinese tourists and students contribute greatly to the US economy, how do you think this law by President trump will affect US productivity and economic growth? Comment particularly on human capital, physical capital, technology, natural resources, and labour
2. With so many Thai businesses closed down during, what do you think is the best way for the economy improve, and to boost productivity. Be specific with your comments about technology, human capital, labour, natural resources, and physical capital.
3. As Stamford International University continues to grow and grow, expanding into post graduate, and doctorate courses, many have asked for higher education to be free. Describe the advantages and disadvantages to the economy, if education was free in Thailand.
