Draw a smooth curve through the top of the bars of the histogram. Write one to two complete sentences to describe the general shape of the curve. (Keep it simple. Does the graph go straight across, does it have a v-shape, does it have a hump in the middle or at either end, and so on?)
ヒストグラムの棒の上端を通る滑らかな曲線を描け。曲線の全体的な形を、1〜2の完全な文で説明せよ。（簡潔でよい。横にまっすぐ続く形か、V字形か、中央またはどちらかの端に山があるか、などを考える。）
