$\backslash$table$[[$Hours$\_$Studied,Average$],[2,57],[3,66],[4,73],[5,76],[6,79]]$

Write the code to convert the file to a data frame with name stud$\_$data

Write the code for creating $x$ data frame $($independent variable$)$ and $y$ data frame $($dependent variable$)$

Write the code to plot a scatter plot between independent and dependent variables

Write the code to find the correlation between variables

Write the code for creating linear regression object

Write the code for training the model using training sets

Write the code for plotting fitted line with title:Hours Studied vs Average, xlabel: Hours Studied, ylabel: Average.

Write the code to add predicted value to the data frame with name pred$\_$average

Add to stud$\_$data the column 'intercept' with the value $1$ and create a new data frame with name independent$\_$variables that contains the columns Hours$\_$Studied and intercept
