Franco has a hat with 9 blue marbles, 4 yellow marbles, and 12 green marbles. he designs a binomial experiment by drawing a marble from the hat, recording whether the marble is green, and then laying the marble aside. he then repeats the process seven times. which statement must be true? the experiment is not a binomial experiment because there is not a fixed number of drawings. the experiment is not a binomial experiment because the probability of choosing a green marble is the same for each drawing. the experiment is not a binomial experiment because the probability of choosing a green marble is not the same for each drawing. the experiment is not a binomial experiment because there are only two possible outcomes for each drawing

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
