Pick the right palette

Consider displaying a raster that contains the proportion of the population that is between the ages of 18 and 24. That is, a value of 0 indicates none of the people in a grid cell are between 18 and 24 and a value of 1 indicates all of the people in a grid cell are between 18 and 24. We've loaded prop_by_age in your workspace if you want to take a look.
