Comment in your own words the value of Minitab in helping the analysis and arriving at a conclusion to the business problem
Minitab enables researchers to statistically analyze and visualize data, identifying trends and patterns that might not be evident otherwise. Specifically, the model summary reveals that the model explains a significant portion of the variance in NOx emissions, with an R-squared value of 63.58%. This relatively high number suggests a strong relationship between humidity and NOx emissions. In conclusion, humidity plays a crucial role in influencing NOx emissions from diesel trucks.
