Select the correct answer. If the data represented by the graph is normally distributed, what are the endpoints of the middle 68% of the data? A bell-shaped graph distributed between the points negative 1.8, 0.4, 2.6, 4.8, 7, 9.2, and 11.4. The shaded areas of the distribution are at (negative 1.8, 0.4), (0.4, 2.6), (2.6, 4.8), (4.8, 7), (7, 9.2), (9.2, 11.4). The median is at 4.8. A. -infinity and +infinity B. -1.8 and 11.4 C. 0.4 and 9.2 D. 2.6 and 7
