Template for Means Testing and Proportion Testing

(Business Statistics - High School, Undergrad, and Grad School)

This is a great template developed by a student in Cornell's Executive MBA program in 2019.

Use the template to:

> Predict the mean of a population using a (small or large) sample

> Predict the proportion of a population using a sample

> Compare means ("matched pairs" (same person before and after and "independent populations (men vs. women, etc.)

> Determine whether there is a difference in proportions across two populations

> Calculate the appropriate sample size

> Hypothesis Testing of many of the above calculations

Chi-squared testing for independence

for example: is there a relationship between gender and political preference?
