The editor of a textbook publishing company is trying to decide whether to publish a proposed business statistics textbook. information on previous textbooks published indicates that 8% are huge successes, 12% are modest successes, 40% break even, and 40% are losers. however, before a publishing decision is made, the book will be reviewed. in the past, 90% of the huge successes received favorable reviews, 70% of the moderate successes received favorable reviews, and 40% of the break-even books received favorable reviews, and 20% of the losers received favorable reviews.

(a) what proportion of textbooks receive favorable reviews?

(b) if the proposed textbook receives a favorable review, how should the editor revise the

probabilities of the various outcomes to take this information into account?

You can find the constant of proportionality by finding the ratio of

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
