MATH266: Discrete Simulations
Example 1: Robin Hood An archer is able to hit the bullseye 70% of the time. Assume each shot is independent of the others. Part I: Identify which distribution should be used in each scenario and calculate the desired probability. The archer’s first bullseye comes on the fifth arrow. The archer’s first bullseye comes within the first five a...

ACS Analysis Example
Working with Complex Survey Data from the American Community Survey The American Community Survey (ACS) is performed annually by the US Census Bureau. Due to its frequency, the ACS can be used to better study trends than the US Census, which occurs every ten years. However, unlike the decennial census data for the ACS is obtained from a random sa...

MATH266: Coverage
Confidence Intervals Confidence intervals present a range of reasonable values for the population. In the frequentist paradigm the population (\(\mu\)) is assumed to be fixed and unknown. We collect a sample of data and estimate \(\mu\) using the sample mean \(\bar{x}=\sum_{i=1}^n x_i\). Generate the Data In this simulation, I will suppress to t...
