Some questions in Part A require that you access data from Statistics for People Who (Think They) Hate Statistics. This data is available on the student website under the Student Test Resources link.

Short Answer Writing Assignment – Both the calculated binomial probabilities and the descriptive statistics from the class database will be used to answer the following questions.

An estimated number of 100,000 children take this exam annually. There is a 1 on 6 probability that the child will qualify due to there being a mere 15000 to 20000 seats. Since these schools have a favourable reputation, the demand for these schools is high. They belong to the top-notch schools in the UK.

Proportion of all business students at Rocky University who were not involved in some type of cheating, are as follows: p1 = 0.1 (9/90).

Blood is drawn four times during the testing hours (30 min, 1 hour, 2 hour, and 3 hour)

It is not easy for a student to know everything on the ACT or SAT. It takes years of dedication starting at a time which a lot students do not even know what the ACT or SAT is yet. Students who are struggling to study begin to memorize possible answers instead of learning the actual concepts and information. Too much cramming could lead to an information

they will pass the course. The probability of not passing if the student does not do the

SAT is one of the most important of any teenager in high school. The SAT determines the fields of college admission and higher education. Moderate of student get into this $500 dollars program for 5 years to study for the SAT. This program helps a student get 1600 on the SAT. That 1600 includes math, reading, and writing. If you get a 800 on everything, then you might just get a scholarship. However, I believe that the SAT is not an accurate valid test for students. Many students have the knowledge to pass, but can also stress about it so much that it messes with them during the test. Also, I don’t think the SAT should affect whether you go into a good college or not. Yet, many student believe that this is their only shoot into

The article that I enjoyed reading the most was the interview of Nicholas lemann. He explained the history of SAT, who wrote it, why we are taking it, and if it is necessary. Nicholas explained that a psychologist that has wrote the SAT, I wasn’t sure why? Why not someone from the department of education, why not a sociologist? He also talked about how SAT was aa test opportunity scholarship for all Ivy League schools which I found insane. Then argued asking is our society obsessed with the SAT? the hysteria that we caused over just an exam, but again its not just an exam it’s the student’s education life depends on it. “The country spends tens of thousands of dollars on test prep, prepping for five years, I think that’s pretty irrational” said Nicholas. Two thing that didn’t occur to him were, one was this whole culture around getting admission, two was the system suppose to scan the people that they weren’t aware of what was going on. Then students we supposed to hope to be picked so they could “make it” as he called it. he also said “these people (referring to those who got picked) would be no better than anybody else.” All students fear that test and someone of them don’t even bother taking because their parents did not have the money to be prepared for it, but that doesn’t mean that they less intelligent than the others. it was funny of him mentioning there is no job in the United States that you have to have gone to X college to get then he said “we’re not at the

The following category discusses the reliability and validity of the SAT. Firstly, the reliability measures the consistency and steadiness of the SAT scores and validity measures how the test is being consumed. The SAT is a reliable test for the reason that if an individual takes the SAT multiple times he or she would receive comparable or higher scores each time the test is given to the individual due to the culture of the test. The SAT is valid since the test is designed to measure an individual cognitive ability and the achievement of students. Research has proved that cognitive test validities are generalizable and predictive of academic performance (Shen, Sackett, Kuncel, Beatty, Rigdon & Kiger, 2012). The SAT shows that more selective

Females: 41.7 / 73.6 = 0.566576 = 56.7 %. The pass score of 56.7% shows that there is evidence of adverse impact: 62.5 / 77.7 = 0.8043758 = 80.4%. The pass rate which is 80.4% indicates that there is no evidence of adverse impact.

The IRS has studied the frequency of errors in tax form B-7014, a two-page form. The probability of error on the first page is 0.1. Given that the first page has an error, the probability that the second page also has an error is 0.15; given that the first page does not have an error, the probability that the second page has an error is 0.1. Let X be the number of pages with errors on a randomly selected form. Find E[X], the expected value for the number of pages with errors. Hint: Use a contingency table or a decision tree to solve this problem.

The SAT is a standardized test widely used for college and university admissions in the United States. It was first introduced in 1926, and its name and scoring system have changed several times throughout the years. Many students around the world that want to pursue post-secondary institutions in the US make it a point to write the SAT at least once in their high school career to better their chances of getting a higher score. This test has three parts to it – one reading, writing and one math. In order to achieve the best score that they can possibly get and be placed in the highest possible percentile, students may decide to attend SAT preparation classes starting from the early years of High/Middle School. The unfortunate reality of these extra preparation courses is that they are quite expensive, and due to this, they mostly cater towards to higher or higher-middle class families. Courses that provide extra preparation such as Ivy Global are not very affordable to many families and so students. According to many statistics and news reports, the higher the test taker’s family income, the higher their scores in the test. This has been a topic of great controversy as we have grown in the modern society

Secondly, question ten was a question that when I administered it to the students, I could sense both their confusion as well as their guessing at an answer. When I administered the posttest, even though the scores on this category went down compared to the posttest, I could tell that not only did they understood the question, but they were confident in their answers and were providing less
