Answer:
The maximum value in the range is 8.113
1 girl in 10 births is a significantly low number of girls.
Step-by-step explanation:
Note that the range rule of thumb says that the range of about 4 times the standard deviation.
We'll use the below formula to determine the standard deviation;
![\begin{gathered} \sigma=\sqrt[]{\lbrack\sum^{}_{}x^2\cdot P(x)\rbrack-\mu^2} \\ \text{where }\mu=\text{ population mean} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/6hpbuejq5duodke5qrgk2st8sb3a9upkdw.png)
Let's go ahead and determine the mean as seen below;



Let's now determine the below;


So the standard deviation will be;
![\sigma=\sqrt[]{29.457-5.233^2}=\sqrt[]{29.457-27.384}=\sqrt[]{2.073}=1.44](https://img.qammunity.org/2023/formulas/mathematics/college/mwvhpavlup4p4wiorbrar306bwou094vst.png)
Let's determine the maximum and minimum value of the distribution as seen below;

We can see from the above that the number of girls born among 10 children should be between the range of 2.353 and 8.113, therefore 1 girl in 10 births is a significantly low number of girls.
The maximum value in this range is 8.113
