Conclusion:

Based on the Two Sample T-Test I conducted, my conclusion for this study is that there is no significant difference for the total amount of money spent per trip to Marc's between men and women. With a P-value of 0.383, the null hypothesis may be rejected at any reasonable level of significance. Although my background research shows there are measurable differences between the genders, this study was likely not sensitive enough to detect them. With a larger sample, and a much wider variety of days to record data, I think differences could be found, but this study is firmly opposite of that hypothesis.
