The goal of this assignment is to formulate reasonable hypotheses based on available data and then test these hypotheses in Excel. You will formulate one hypothesis that can be tested with an independent samples t-test and one hypothesis that can be tested with a chi-square test of independence. The data represents results from a survey with households with families. The data file is included in the attached file.
For this assignment you will formulate two hypotheses based on the variables includes in the attached dataset, and provide an example of a marketing consequence (for a particular company or a group of companies) if you were to find support for your alternative hypotheses. In the next step, you will conduct hypotheses tests with the available sample data, and finally, you will interpret the results from your tests. Below I have provided step-by-step instructions.
