The document discusses building simple linear regression models to predict delivery time using sorting time and to predict salary hike using years of experience. It performs EDA, builds linear regression models, evaluates the models, and makes predictions for both tasks.

(a) Use the lm() function to perform a simple linear regression with mpg as the response and horsepower as the predictor. Use the Summary() function to print the results. Comment on the output. For example: i. Is there a relationship between the predictor and the response? ii. How strong is the relationship between the predictor and the response?
