Question

on below to answer the following 3 questions. Based on data from out of 3,952,841 births: m the Center of Disease Control on births in the U.S. in recent years, of 456,553 births are preterm (under 37 weeks) 130,839 births are to twins 4919 births are to triplets and higher order multiple births. 49. Based on the available data, what is the estimated probability of a full-term birth? a. 0.8845 b. 0.1155 c. 3,496,288 50. Based on the available data, what is the estimated probability of a multiple birth (i.e., more than one child)? a. 0.0331 b. 0.0012 c. 0.0343 d. 0.0376 51. Based on the available data, what is the estimated probability that a multiple birth is to triplets and higher order? a. 0.0362 b. 0.0376 c. 0.0012

Explanation / Answer

n = total number of birth = 3952841

m= number of births are preterm = 456553

hence number of full term birth = 3952841 - 456553 = 3496288

Q. 49 )

Estimated probability of full-term birth = 3496288 / 3952841 = 0.8845

Correct Answer : a 0.8845

Q.50)

Number of multiple birth ( more than one child) = 130839 + 4919 = 135758

P ( Number of multiple birth(more than one child)) = 135758 / 3952841 = 0.0343

Correct Answer : c 0.0343

Q.51)

Number of birth are triplets and higher order multiple births = 4919

P ( Multiple birth is a triplet and higher order birth ) = 4919/3952841 = 0.0012

Correct Answer : c 0.0012
