	Exact binomial test

data:  11 and 24
number of successes = 11, number of trials = 24, p-value = 0.8388
alternative hypothesis: true probability of success is not equal to 0.5
95 percent confidence interval:
 0.2555302 0.6717919
sample estimates:
probability of success 
             0.4583333 

Probably not. Or at least we can’t conclude that from the data. ¯\_(ツ)_/¯

I didn’t know that Rómendacil II was born with another name. Got the rest. :)
