A pharmaceutical company claims that only 5 percent of patie

A pharmaceutical company claims that only 5 percent of patients experience nausea when they take a particular drug. In a research study, n = 100 patients were given this drug and 8 experienced nausea. Assuming that the company\'s claim is true, what is the probability of 8 or more patients experiencing nausea?

Solution

n =100

p = prob for nausea = 5% = 0.05

If companies claim is true x = no of persons having nausea follow a binomial distribution with

p =0.05 and n =100

the probability of 8 or more patients experiencing nausea

=P(X>=8)

= 0.1280
