Assume that 10% of subjects treated with a certain drug experienced the adverse reaction of nausea (based on clinical trials}. a. Find the probability that among 250 randomly selected subjects treated with the drug: exactly 23 of them experience nausea. b. Find the probability that among 250 randomly selected subjects treated with the drug: the number who experience nausea is 23 or fewer. c. Does it appear that 23 cases of nausea among the 250 subjects is significantly low? a. Find the probability that amosg 250 randomly selected subjects treated with the drug: exactly 23 of them experience nausea. The probability of exactly 23 is . (Round to four decimal places as seeded.) b. Find the probability that amosg 250 randomly selected subjects treated with the drug: the number who experience nausea is 23 or fewer. The probability of 23 or fewer is . Round to four decimal places as needed.) c. Does it appear that 23 cases of nausea among the 250 subjects is significantly low? Y because the probability of this event, . is Y than the probability cutoff that corresponds to a significant event: which is Round to four decimal places as needed.)
