Inference for Two-Way Tables
In this assignment you will analyze people who use the World Wide Web to collect information on travel and compare them to those who use other resources, using the techniques you learned in this module.
Construct a two-way table based on a business problem statement giving observed counts.
Determine the applicable degrees of freedom for the model.
Compute the expected counts for the two-way table.
Compute the chi-square test statistic for the two-way table.
Use the chi-square distribution for hypothesis testing involving categorical variables.
Compute the observed level of significance (p-value) based on the computed chi-square test statistic.
Based on your statistical analysis results, be able to prepare a business report presenting the conclusions of the analysis.
