Imagine a surgery that is known to have a 10% chance of serious side effects. An internal hospital review shows that four out of eight of a particular doctor's patients have these side effects. If we want to know whether this doctor's patients are experiencing usually low or high rates of side effects, what would the P-value of a binomial test of this hypothesis be?
