The marketing team is given a survey to analyze. The survey was conducted within a city

and asked people's interest in a potential product (similar to the one we had in class). The assistant analyst

complied the data to reach the following table. The table shows, for example, for consumers who were

surveyed and had income below $50k, 90 expressed interests while the rest 225 said they were not interested

in the product.

Suppose we are given an advertising budget spend to make consumers aware of our new product; the

cost of advertising per consumer is the same for any income bracket.
