Eagle flu can be devastating for those who are hospitalized. Researchers at JJ Health Services took a random sample of n=2561 hospitalized Eagle flu patients out of a very large population of hospitalized Eagle flu patients. Of these x = 1497 patients showed a symptom of very high fever (VHF). Let p be the (unknown) true proportion of hospitalized Eagle flu patients who show a symptom of VHF. We want to estimate p. X is the random variable representing the number of sampled Eagle flu patients with VHF a) What type of probability distribution does X have? binomial Weibull     gamma Poisson exponential
