Gender: 63% of customers are female, and 37% are male.

Its main objective is to identify whether the means of two groups are statistically different from each other (Trochim, 2006). In this case, the t-test must determine whether men are more likely to travel longer distances to go to the store than women are.
The results of the t-test reveal that although a small percentage of men is more likely to travel a longer distance to go to a store in comparison with women, the difference is not significant.
Another hypothesis proved with the use of the t-test is represented by the fact that regular customers have a neutral opinion on the prices of the products in these stores.
