second opinion. 1 is B and 2 is B as well? is that right?

1. Consider the following scatterplot of midterm and final exam scores for a class of 15 students 100 x 100x Final exam 50 x. 100 50 Midterm exam score Which of the following are true statements? L. The same number of students scored 100 on the midterm exam as scored on the final exam. III. Students who scored higher on the midterm exam tended to score higher on the final exam. III. The scatterplot shows a moderate negative correlation between midterm and final exam score (B) I and III (E) None of the above gives a complete set of true responses (C) II and III (A) I and II (D) I, II and I11 2. Suppose the correlation between x and y is negative. Given two points from the scatterplot, whis following is possible? 1. The first point has a larger x-value and a smaller y-value than the second point. IL. The first point has a larger x-value and a larger y-value than the second point. III. The first point has a smaller x-value and a smaller y-value than the second point. (A) I only (D) I and II (C) II only (B) II only (E) I. II and III

Solution

I. True

II. False

III. True

So option B I and III

--------------------------------------------

III is right

Hence option C
