The faithful data set contains two variables: the duration (eruptions) of the eruption and the time until the next eruption (waiting).

a) Make a scatterplot of these two variables and comment on any patterns you see.

b) Remove the first value of eruptions and the last value of waiting. Make a scatterplot of these two vectors.

c) Which of the two scatterplots reveals a tighter relationship? What does that say about the relationship between eruption duration and the interval between eruptions?
