Case Study #1.2.1

Random Samples

Case Description: We will take an actual bowl, which contains actual chips of various colors. We will draw samples of draws with replacement from this bowl. We will examine these samples.

Case Objectives:

Understand Random Samples and Draws with Replacement.

Draw random samples (draws with replacement) of size 25, 60. Summarize appropriately each sample.

The structure of the bowl, expressed as color proportions, determines the basic structure of samples drawn from the bowl. The random samples reflect (albeit imperfectly) the actual structure of the bowl.
