Answer:
C. No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.
Step-by-step explanation:
Given that an experimental drug is administered to 90 randomly selected individuals, with the number of individuals responding favorably recorded.
We find here the no of trials are 90 but we cannot say the probability is the same for all trials.
In other words, each individual may have a different probability to respond.
Since p , the success for each trial may differ for each trial binomial cannot be accepted
C. No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.
