Jada blew six bubbles. And Tara blew one bubble. And we have one, two, three, four data points. So let's divide by four. And so this is going to be equal to 4 plus 5 is 9, plus 6 is 15, plus 1 is 16. So it's equal to 16 over 4, which is 16 divided by 4 is equal to 4. So the mean number of bubbles blown is 4.
