Problem definition and business intelligence
This study aimed to answer the following research questions;
1. Are there significant differences in the sale amounts for the different products?
This particular questions aims to find out whether some of the products are doing better
than the others. This information is useful to the company to come up with ways of either
maintaining the good sales of a product or identifying why a given product is not
performing. Analysis of variance will be used to analyse this problem based on the factor
that there are more than two product categories.
2. Are there significant differences in product purchase between the male and the female?
This particular questions aims to find out whether the purchasing power of males and
females is the same or not. Knowing this is important for the company to come up
promotional sales that target various gender groups. An independent samples t-test will
be used to test this. This test is appropriate based on the fact that there are two unrelated
groups which are to be compared.

This particular questions aims to find out whether the purchasing power of the single
customers and the married customers is the same or not. Knowing this is important for
the company to come up promotional sales that target various groups of people. For
