The squares of the 60 plasma silicone levels in DB5 are (• 9 225, 169, 1521, 400, 1521, 1764, 576, 324, 144, 676, 100, 121,225, 361,729, 784, 121, 121, 324, 324, 576, 2304, 484, 729, 361,324, 1024, 961,361, 441,441, 576, 100, 144, 784, 625, 484, 441,529, 484, 484, 576, 1444, 2025, 529, 484, 324, 225, 16, 196, 576, 400, 324, 576, 225,361,676, 900, 484, 576. Plot a relative frequency distribution of these squares using intervals: 0-0.02, 0.02-0.04,

..., 0.22-0.24. Does it appear more similar to the normal or the chi-square probability distribution in Section 2.8? Why?
