Exercise

# Default trend lines

`ggplot2`

gives us powerful tools to visualize our data and "see" what is going on.
However, sometimes we need to wrangle our data to give us what we need.
During this exercise, you will look and see if the length of commutes changes the chance somebody rides the bus.
You will do this by changing the points to be non-overlapping (or jittered) using `geom_jitter()`

and adding smoothed trend line with `geom_smooth()`

.

Instructions

**100 XP**

- Using the data.frame
`bus`

, plot`MilesOneWay`

on the x-axis and`Bus2`

on the y-axis. - Jitter the width of the data by
`0`

and the height by`0.05`

. - Label the axes on the plot. Use
`"Probability of riding the bus"`

on the y-axis and`"One-way commute trip (in miles)"`

on the x-axis. - Save this plot as
`gg_jitter`

then add`geom_smooth()`
