The objective of this project is to uncover the relationship within the sample distribution from the 1974 Motor Trend US magazine dataset. This dataset includes measurements of fuel consumption and 10 aspects of automobile design and performance for 32 vehicles (models from 1973-74). One of the critical features considered by the automotive industry is the mileage per gallon (Mpg), which indicates how far a vehicle can travel on one gallon of fuel. Understanding how Mpg relates to vehicle weight (in 1000 lbs) is crucial for manufacturers in designing models that cater to a broad customer base. As a statistician, my focus is on exploring the association between Mpg and vehicle weight in this context.

This study enrolled 236 adult patients undergoing elective thoracic surgery requiring a double-lumen endotracheal tube. Gender, physical status, BMI, age, Mallampati score, smoking status, preoperative pain, surgery size, intervention and the outcomes (cough, sore throat and pain swallowing at various time points) are provided. The dataset is cleaned and complete (missing outcomes for 2 patients).
