A report gave the following information on births in a certain country during a particular year.
| Type of Birth | Number of Births |
|---|---|
| Single birth | 3,838,214 |
| Twins | 125,336 |
| Triplets | 4,233 |
| Quadruplets | 236 |
| Quintuplets or higher | 47 |
(a)
Use this information to estimate the probability that a randomly selected pregnant woman who gave birth in this year delivered twins. (Round your answer to three decimal places.)
(b)
Use this information to estimate the probability that a randomly selected pregnant woman who gave birth in this year delivered quadruplets. (Round your answer to six decimal places.)
(c)
Use this information to estimate the probability that a randomly selected pregnant woman who gave birth in this year gave birth to more than a single child. (Round your answer to three decimal places.)
Homework Answers
There are total number of births= 3968066
a)
P(twins) = 125336/3968066
= 0.032
b)
P(quadruplets) = 236/3968066
= 0.000059
c)
P(more tan a single child) = (125336 + 4233 + 236 +
47)/3968066
= 0.033

Is smoking during pregnancy associated with premature births? To investigate Type numbers in the this question, researchers selected a random sample of 130 pregnant women who were smokers. The average pregnancy length for this sample of smokers Part 2: 5 points was 260 days. From a large body of research, it is known that length of human pregnancy has a standard deviation of 16 days. The researchers assume that smoking does not affect the variability in pregnancy length. ab Part...
