Question
This Question: 1 pt 10 of 15 (8 complete) This Test: 15 pts A study found that 37% of the assisted reproductive technology ART cycles resulted in pregnancies. Twenty-six percent of the pregnancies resulted in multiple births. ARI (a) Find the probability that a random selected ART cydle resulted in a pregnancy and produced a multiple birth. (b) Find the probability that a randomly selected ART cycle that resulted in a pregnancy did not produce a multiple (c) Would it be unusual for a randomly selected ART cycle to result in a pregnancy and produce a multiple birth? Explain (a) The probability that a randomly selected ART cycle resulted in a pregnancy and produced a multiple bith is (Round to the nearest thousandth as needed) (b The probability that a randomly selected ART cycle that resulted in a pregnancy did not produce a multiple birth is Round to the nearest thousandth as needed) (e) Would t be unusual for a randomly selected ART cycle to result in a pregnancy and produce a multiple answer below O A. Yes, this is unusual because the probability is less than or equal to 0.05 Yes, this is unusual because the probability is not less than or equal to 0 0s5 ° C. No this is not unusual because the probability is less than or equal to 0.05 ( D. No, this is not unusual because the probability is not less than or equal to 0 05 to
Explanation / Answer
a) required probability = 0.37 * 0.26
= 0.0962
b)
(1-0.26)
= 0.74
c)
since 0.0962 > 0.05
it is not unusual
D) is correct
