Determine whether the random variable X has a binomial distribution. If it does, state the number of trials n . If it does not, explain why not. Twenty students are randomly chosen from a math class of 70 students. Let X be the number of students who missed the first exam. Choose the statement The random variable (?CHOOSE ONE?) a binomial distribution. Choose the statement that explains why does not have a binomial distribution. More than one may apply. A)...

Use simulations to prove that the binomial distribution is correct. The binomial distribution has two parameters n and p. There are n trials and each has two possible outcomes, with probability p for “success” and 1-p for “failure”. The binomial gives the probability distribution for the number of successes in n trials. You will conduct simulations with r replicates, where each simulation replicates does n simulated “coin flips”. You will add up the number of successes in each coin flip,...
