Here is a sample of amounts of weight change (kg) of college students in their freshman year: 10, 5, 1, 5, where - 5 represents a loss of 5 kg and positive values represent weight gained. Here are ten bootstrap samples: {10, 10, 10, 1}, {10, 5, 1, 10}, {10, 5, 5, 1}, {5, -5, 1, 10}, {1, 1, 1, 5}, {5, 5, 5, -5}, {10, 5, -5, 1}, {-5, 5, 5, 5}, {-5, 1, 5, 5}, {5, 10, 10, 10). Complete parts (a) and (b) below.
