Here is a sample of amounts of weight change(kg) of college students in their freshmanyear: 14, 4, 0, 6, where 6 represents a loss of 6 kg and positive values represent weight gained. Here are ten bootstrapsamples:

{14,14,14,0}, {14,6,0,14}, {14,6,4,0}, {4,6,0,14}, {0,0,0,4}, {4,6,4,6}, {14,4,6,0}, {6,4,6,4}, {6,0,6,4}, {4,14,14,14}.

Complete parts(a) and(b) below.
