9. This question involves the use of multiple linear regression on theAuto data set. (using R script)

  1. (a) Produce a scatterplot matrix which includes all of the variables in the data set.

  2. (b) Compute the matrix of correlations between the variables using the function cor(). You will need to exclude the name variable, which is qualitative.

  3. (c) Use the lm() function to perform a multiple linear regression with mpg as the response and all other variables except name as the predictors. Use the summary() function to print the results. Comment on the output. For instance:

1. The correlation for a set of data is r=0.99. The residuals plot for that set of data shows a curved pattern, like a "U" shape. What conclusion about the data do you reach based on this information? A. The association between the explanatory and response variables is strong, positive and linear. B. It is not appropriate to use a linear regression model as the scatterplot is curved. C. The association between the explanatory and response variables is strong, positive...

2. Consider the data set has four variables which are Y, X1, X2 and X3. Construct a multiple regression model using Y as response variable and other X variables as explanatory variables. (a) Write mathematics formulas (including the assumptions) and give R commands to obtain linear regression models for Y Xi, i =1, 2 and 3. (b) Write several lines of R commands to obtain correlations between Xi and Xj , i 6= j and i, j = 1, 2,...

In R-studio , Use a for loop to iterate over all rows of the mtcars dataset to create a car objectfor each row. Use the name of the row, and the values for mpg, cyl, and hp. You canignore the columns not needed for the construction of our car object. After creatingthe car object use the print() function to print it. The mtcars data set is already integrated in R. That is what I am using for this question
