Biostatistics Bios600.001 Second Semester, 2009-2010 Home Work 3: Introduction to Statistical Inference Instructions: This problem set consists of one problem. You’ll be asked to submit your work in hard copy in the form of responses to the following steps and questions. Due Date: 9:30 am in class on Feb 11, 2010. Problem 1. Sampling Distributions Learning Objectives: Students who successfully complete this exercise will be able to: generate random numbers and appreciate variation among multiple observations of a random process; explain the implications of the Central Limit Theorem in determining the sampling distribution of the mean of n observations. Scientific Background: Your job is to determine the sampling distribution of a mean of N times spent waiting for a bus in Chapel Hill. The bus comes every 32 minutes, but you have no idea when the schedule starts, and it varies randomly from day to day. Thus, the distribution of waiting times is realistically close to a “uniform” that is, all times between 0 and 32 minutes have equal chance of occurring. In this experiment, you will investigate the
