Question

determine whether the statement makes sense or does not make sense, and explain your reasoning
my math teacher gave a very difficult exam for which the distribution of scores was skewed to the right

choose the correct answer below

a. the statement does make sense because a large number of student scores would be piled up at the low end of the distribution, and low student scores would be at the high end

b. the statement does not make sense because a large number of student scores would be piled up at the high end of the distribution, and low student scores would be at the low end. thus, the distribution would be skewed to the left

c. the statement does not make sense because a large number of student scores would be piled up at the low end of the distribution, and low student scores would be at the high end. thus, the distribution would be skewed to the left

d. the statement does make sense because a large number of student scores would be piled up at the high end of the distribution, and low student scores would be at the low end

Explanation:

When an exam is very difficult, most students will score low (scores piled up at the low - end of the distribution). In a skewed - to - the - right distribution, the tail is on the right (higher values). But for a difficult exam, we expect a few high scores (tail on the right) and most scores on the low side.

Answer:

A. The statement does make sense because a large number of student scores would be piled up at the low end of the distribution, and few student scores would be at the high end.
