MEAN =E(X)=4.0
E(X^2)= 18.217
V(X)= 18.217-16
= 2.217
std= sqrt(2.217)= 1.5
As per the Q&A guidelines I have done the first question please re post the rest. Thank You

The accompanying table describes results from groups of 10 births from 10 different sets of parents. The random variable x represents the number of girls among 10 children. Use the range rule of thumb to determine whether 1 girl in 10 births is a significantly low number of girls. Click the icon to view the table Use the range rule of thumb to identify a range of values that are not significant. The maximum value in this range is girls....
The accompanying table describes results from groups of 10 births from 10 different sets of parents. The random variable x represents the number of girls among 10 children. Use the range rule of thumb to determine whether 1 girl in 10 births is a significantly low number of girls.
