The dataset 'Delivery' shows the cost of delivery for different locations in the state of Karnataka >Charges-Cost of Delivery. >Distance-Distance to the delivery address. >Weight- Weight of the consignment > Boxes - Number of boxes. A) Construct a simple linear regression model to understand the effect of distance on delivery charges. Based on results obtained, infer the relationship between delivery charges and distance. (3 marks) B) Construct a multiple linear regression model to assess effect of different variables like distance, weight and boxes. Detail your interpretations.
