# First random sample, second random sample

Now, you will dive in to understanding how linear models vary from sample to sample. Here two random samples from a population are plotted onto the scatterplot. The population data (called `popdata`

) already exists and is pre-loaded, along with `ggplot`

and `dplyr`

.

Instructions 1/3

**undefined XP**

- Using the whole dataset,
`popdata`

, plot`response`

vs.`explanatory`

. - Add a point layer using
`geom_point()`

. - Add a smooth trend layer using
`geom_smooth()`

, with the linear regression method,`"lm"`

, and no standard error ribbon,`se = FALSE`

.
