# Now it is your turn
# make a model of parking prices vs soda prices
# first name the 4th column a vector park 
# and last column vector sodacost


# now run the linear model with the lm() command
# and call the result model2


# now find summary statistics on model2
# and plot the scatterplot
# with line of best fit on it


# now find the residuals and plot them
# on the y axis, with sodacost on the
# x axis for the residual plot
# and be sure to include x axis line
