Could anyone help me with Exercise 3 - I'm not sure which function to use to plot the proportion, and with problem 3 at the end - I'm not sure how to plot a ratio? Thank you!
How about this?
The boy-to-girl ratio can be obtained by:
"present$boys/present$girls"
Then, plug is this into the second argument of the "plot" function in the Exercise 2.
Of course, we need to replace the first argument with respect to the "present" data.
