37. 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 22 of them experience nausea. b. Find the probability that among randomly selected subjects treated with the​ drug, the number who experience nausea is 22 or fewer. c. Does it appear that 22 cases of nausea among the 250 subjects are significantly​ low?   a. Find the probability that among 250 randomly selected subjects treated with the​ drug, exactly 22 of them experience nausea.    b. find the probability that among 250 randomly selected subjects treated with the drug the number who experience nausea is 22 or few.   the probability of 22 or few is_________.   c. does it appear that 22 case of nausea among the 250 subjects is significantly low?   1.____________________________ because the probability of this event,__________, is (2)___________ than the probability cutoff that corresponds to a significant event, which is (3)_________ round to 4 decimal place              The probability of exactly 2222 is nothing. ​(Round to four decimal places as​ needed.)

The 2015 National Vital Statistics Report provides information on how the nearly four million live births that occurred in 2014 broke down by birth order. Choose at random a baby born in the United States in 2014. Baby's birth order Probability mean = 1 2 0.391 0.319 The few babies who were 9th or more in birth order are included in the "8" birth order group. In 2014, 39.1% of the nearly 4 million live births in the United States were to first-time mothers. 3 5 6 7 4 0.168 0.072 0.028 0.012 0.005 standard deviation = What are the properties of the sampling distribution of the proportion of births to first-time mothers in random samples of 500 births from 2014? (Enter your answer for the mean rounded to three decimal place and your answer for the standard deviation rounded to four decimal places.) 8 0.005
