Dichotomizing variables
Now that we've cleaned up our question names, let's work on the response variable. In the original analysis, they looked at the percent of people considering a behavior somewhat or very rude. To replicate this, we'll need to change our rude variable from the current responses to one that combines the somewhat and very rude answers.

mutate(response_var = str_replace(response_var, 'on a plane', '')) %>%
# Remove rows that are NA in the value column
___ %>%
# Dichotomize the value variable to make a new variable, rude
mutate(rude = if_else(value ___ c('No, not rude at all', 'No, not at all rude'), ___, ___))
