Given the following two regression models to predict college gas consumption, mpg   In the table below, name and then report three different criteria of model selection from the above output for model 1 and model 2 (plus their respective values – keep all the decimal points). Each row is dedicated to one of the three model selection criteria. The name of model selection criterioon should be specified in column 1 and the corresponding values of those criteria for model 1 and model 2 should be typed in columns 2 and 3, respectively. Then within each row, compare the criterion between model 1 and model 2 and say which model you pick as a better predictive model based on each criterion (type whether you picked model 1 or model 2 in column 4). List below 3 criteria in any order Value of criterion index for Model 1 Value of criterion index for Model 2 Which model has the best predictive power based on the reported criterion index in each row (Type Model 1 or Model 2) Criterion 1 name Criterion 2 name Criterion 3 name    

Which Data Visualization technique is best suited for comparing data across different categories or groups?

A data set comprises fuel consumption and 3 aspects of automobile design and performance for 32 automobiles. The modeling objective is to explain an automobile’s fuel consumption in miles/(US) gallon (mpg.)  using predictors: CYL: number of cylindersWT: weight in pounds (1000 lbs.)DP: displacement in cubic inches (cu in.) The R output of a simple linear regression with weight (WT) as the predictor is given below   What percent of raw variability in fuel consumption is accounted for by the regression model?
