Question

In a recent year, about 37% of all infants born in a country were conceived through in-vitro fertilization (IVF). Of the IVF deliveries, about twenty-six percent resulted in multiple births. (a) Find the probability that a randomly selected infant was conceived through IVF and was part of a multiple birth. (b) Find the probability that a randomly selected infant conceived through IVF was not part of a multiple birth. (c) Would it be unusual for a randomly selected infant to have been conceived through IVF and to have been part of a multiple birth? Explain. (a) The probability that a randomly selected infant was conceived through IVF and was part of a multiple birth is . (Round to the nearest thousandth as needed.) (b) The probability that a randomly selected infant conceived through IVF was not part of a multiple birth is . (Round to the nearest thousandth as needed.) (c) Would it be unusual for a randomly selected IVF cycle to result in a pregnancy and produce a multiple birth? Explain. Choose the correct answer below. A. Yes, this is unusual because the probability is less than or equal to 0.05. B. No, this is not unusual because the probability is not less than or equal to 0.05. C. No, this is not unusual because the probability is less than or equal to 0.05. D. Yes, this is unusual because the probability is not less than or equal to 0.05.
