Hypothesis Testing

a. It is hypothesized that customers in the Corporate segment are more likely to place larger orders than their consumer counterparts. Thus, the average quantity ordered for corporate customers is expected to be greater than that for general consumers. This contention will be investigated through an appropriate hypothesis test using sample data.

b. Another hypothesis suggests that the average profit per transaction differs between technology and office supplies categories. We will test if there is a significant difference in the average total profit for technology and office supplies.

Correlation and Regression

Investigate the relationship between Sales and Profit. Estimate the linear relationship between the two variables and utilize the model to predict profit from sales.

Full Regression Analysis With Appropriate Discussion Should Include:

1. Scatterplot and brief discussion 
2. Estimate of the linear regression model
3. Coefficients of correlation and determination 
4. Test of the hypothesis that there is no linear relationship between sales and profit.

Conclusion Provide

a concise summary of the findings, emphasizing interpretation and analysis rather than mere computation of statistics. Discuss the main features of the tables and graphs constructed.

Video Presentation of Results Prepare a video presentation showing the results via PowerPoints or similar software, explaining the findings in a non-technical style suitable for a senior manager`s understanding. Appendices should include formulae, calculations, and
