Chapter PI, Problem 2RE

(a)

To determine

To explain is the overall rate the average of the other three rates.

Answer to Problem 2RE

Yes, it is.

Explanation of Solution

It is given in the question, the results of American association report about the infant mortality rate for twins carried for the full term of normal pregnancy are shown in the table broken by the level of prenatal care the mother had received. Thus, let us find out the average of the infant mortality rate as:

  $\begin{array}{l}\frac{5.4+3.9+6.1}{3}\\ =5.1\end{array}$

Thus, yes, this is the overall rate, the average of the other three rates because it gives the average of the rates given in the question.

(b)

To determine

To explain do these results indicate that adequate prenatal care is important for pregnant women.

Answer to Problem 2RE

Yes, it is.

Explanation of Solution

It is given in the question, the results of American association report about the infant mortality rate for twins carried for the full term of normal pregnancy are shown in the table broken by the level of prenatal care the mother had received. Yes, these results indicate that adequate prenatal care is important for pregnant women because as given in the table for the adequate prenatal care for the pregnancy the infant mortality rate is very low than the other prenatal care.

(c)

To determine

To explain do these results suggest that a woman pregnant with twins should be wary of seeking too much medical care.

Answer to Problem 2RE

No, it is not.

Explanation of Solution

It is given in the question, the results of American association report about the infant mortality rate for twins carried for the full term of normal pregnancy are shown in the table broken by the level of prenatal care the mother had received. No, these results do not suggest that a woman pregnant with twins should be wary of seeking too much medical care because the intensive prenatal care’s infant mortality rate $5.4$ is higher than the adequate prenatal care’s infant mortality rate $3.9$ . Thus, the adequate prenatal care is important not too much intensive prenatal care.
