Statement (1) is insufficient, as it jaust tells us the average value - not a word about the scores histogram.
Statement (2) would be suffcient only if we knew how many students scored exactly the average value and how many did actually take the test. As we don´t know either of these, even taken together the statements are insuffcient - answer E.
