4. Given the sаme Cоefficient Tаble аs in Questiоn 3, what is the meaning (in wоrds) of the coefficient, 15.58, for Time in month?
Dаtа Anаlysis Prоblem: Predicting Fuel Cоnsumptiоn Using Multiple Linear Regression You are provided with the Auto MPG Dataset (the dataset below), which contains data on the fuel consumption (measured in miles per gallon, or mpg) for various car models. The dataset includes the following attributes: auto-mpg.xlsx Cylinders: Number of cylinders in the engine. Displacement: Engine displacement in cubic inches. Horsepower: Power of the engine in horsepower. Weight: Weight of the car in pounds. Acceleration: Time taken to accelerate from 0 to 60 mph (seconds). Model Year: Year the car model was manufactured. Origin: Country of origin of the car (e.g., USA, Europe, Japan). 1 represents USA, 2 represents Europe, and 3 represents Japan. The dataset consists of 110 samples, each with 8 attributes, including mpg as the dependent variable. Task: 1. Fit a Multiple Linear Regression Model: Use the dataset to build a multiple linear regression model where the dependent variable is the fuel consumption (i.e., mpg), and the independent variables are the features provided (cylinders, displacement, horsepower, weight, acceleration, model year, origin). Generate the result output in Excel. Note: please do not include “car names” into the analysis. 2. Identify Key Factors: Based on the model you fit, determine and discuss which factors (independent variables) have the significant influence on fuel consumption (i.e., mpg). Specifically, look at the model's coefficients and statistical significance (p-values) to assess the impact of each factor. 3. Analysis Report: Interpret the regression coefficients for the significant independent variables. Explain how these factors affect the charges (positively or negatively). Discuss whether the model is a good fit of the data. Please upload your Excel spreadsheet for this problem.
