Here is a sample of amounts of weight change (kg) of college students in their freshman year: 10, 9, 1, – 7, where -7 represents a loss of 7 kg and positive values represent weight gained. Here are ten bootstrap samples: {10, 10, 10, 1}, {10, - 7, 1, 10}, {10, - 7, 9, 1}, {9, – 7, 1, 10}, {1, 1, 1, 9}, {9, - 7, 9, - 7}, {10, 9, - 7, 1}, {- 7, 9, - 7, 9}, {– 7, 1, - 7, 9}, {9, 10, 10, 10}. O Complete parts (a and (b) below. a. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the mean weight change for the population. 0 kg

Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.
