Many graduate school programs in the United States require applicants to take the Graduate Record Exam, also called the GRE. One part of the exam, the GRE-Quantitative test, assesses students' level of quantitative reasoning and thinking - exactly the skills we are building in our class this semester. The highest score possible on the GRE-Quantitative test is a score of 800. Many graduate schools think that a score of 700 or higher on the GRE-Quantitative test shows that the applicant has strong quantitative skills. The table shows the number of people who took the GRE between 2003 and 2006 who had GRE-Quantitative test Scores of 700 or higher.

Is Homework Truly Beneficial? Two decades ago, researchers believed that homework had a negative impact on students’ physical and emotional health, yet students are still bogged down with hours of homework as early as the second grade. According to research by several universities, elementary students spend an average of 3 hours a week doing homework. The same studies revealed that the average high school student spends over 22 hours a week on homework. In fact, students today spend more than double the time on homework than students two decades ago. Sadly, as time spent on homework doubles, student performance continues to decline. So, how then is homework helping? Homework is harmful and not the key to student success. 2 Select the correct answer. How does the writer introduce the claim? A. by using research to set the context for the argument against homework B. by telling a short personal story about her struggles with homework C. by comparing…

Show all your steps please and explain Do it in digital format and upload screenshots of every element you use, place all the equations you use. THANK YOU In a European university, we want to test the hypothesis that the intelligence quotient (IQ) of the students who study physics and mathematics is different from the average IQ of the entire university, for which a sample of 30 students from these two careers is taken. If the average IQ of the entire university is 118, construct two decision rules that allow this hypothesis to be tested, a) Considering values of alpha = 0.01 b) Considering values of alpha=0.40 Suppose that the results obtained in the sample are the following and have a normal distribution: 147.5, 144.7, 149.2, 144.5, 143.6, 139.6, 151.6, 140.6, 151.1, 139.2, 140.8, 156.9, 158.0, 145.3, 146.1, 148.5, 145.0, 143.2, 141.4, 149.6, 152.2, 145.6, 149.4, 151.3, 150.0, 151.5, 146.2, 147.7, 148.9, 146.6
