I for a Binomial Distribution, Each Trial Has a Known

question 22

Multiple Choice

i. For a binomial distribution, each trial has a known number of successes. For example, a four question multiple-choice test can only have zero, one, two, three and four successes (number correct) . ii. To construct a binomial probability distribution, the number of trials and the probability of success must be known.
iii. A binomial distribution has a characteristic that the trials are independent, which means that the outcome of one trial does not affect the outcome of any other trial.

• A) (i), (ii), and (iii) are all correct statements.
• B) (i) is a correct statement but not (ii) or (iii).
• C) (i) and (iii) are correct statements but not (ii).
• D) (ii) and (iii) are correct statements but not (i).
• E) (i), (ii), and (iii) are all false statements.
