The model you put together in the last exercise resulted in two vectors: (1) proportion_clicks that represents the uncertainty regarding the underlying proportion of clicks and (2) n_visitors which represents the uncertainty regarding the number of visitors you would get. We have now put these vectors into a data frame for you called prior.

Take a look at the first rows of prior using the head() function.
