Suppose 10% of cases of a particular type of cancer go into remission (the cancer is no longer active). If we run a drug trial on 500 individuals and find that 75 of those cases go into remission, should we expect that the difference is due to the drug or just chance?

To answer this, you should have found the probability of observing75 or more individuals going into remission using the binomial distribution. What is that probability?

2. Given the previous probability, should we expect that the difference is due to the drug or just chance?
