Question 3 (Mandatory) Which of the following descriptions regarding hist() in R is correct? 'xlab' is used in the plot function to add both x-axis and y-axis labels. 'title' is used in the plot function to add the title. 'xlim' is used to control the range of the x-axis. hist() can only generate a frequency plot, but not a density plot.
