(i) Suppose for a sample of 12 students, the average scores in Math and English are 85 and 73 respectively, and the regression equation relating the Math scores (x) to English scores (y) is given by:  y′=0.7+0.85x. Assuming that there is a significant linear correlation between the Math and English scores, predict the English score of a student who scored 91 in Math. Round your answer to the nearest whole number.

(ii) What would the answer in part (i) be if a previous study concluded that the linear relationship between Math and English scores in general is not significant?

For the 40 students in a class, the results of their second English test are plotted against the results of their first English test. It was found that for each student, the result of the second test is better than that of the first test (i.e., the second test score is higher). Which of the following must be true about the relationship between the students’ second test results and their first test results? I. If student A scores better than...

Suppose researchers want to know the effect of elementary school class size on students’ math scores(total score is 100), intuitively they think there exists a negative linear relationship between class size and students’ math scores. The researchers want to know the marginal effect of class size on student’s math scores. 1) Based on the background information, design an linear regression model for this research question, and briefly explain your dependent variable, independent variable and the meaning of the parameters.

Colleges use SAT scores to predict how students will perform at the college level. Suppose the entering freshmen at a certain college have mean SAT Scores of 1200, with a standard deviation of 113. In the first semester these students attained a mean GPA of 2.57, with a standard deviation of 0.46. A scatterplot showed the association to be reasonably linear, and the correlation between SAT score and GPA was 0.39. a) Write the equation of the regression line. b)...

In a study of Math SAT scores done in 2010, the investigators computed the average Math SAT score ( A i )in each of the 50 states and D.C. and the percentage ( P i )of high school seniors in each state that took the test that year. They found that the correlation between the variables A and P was r = -0.77. (a) Does this mean that the the test scores were better on average in states where fewer...
