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.
(Round to one decimal place as needed.)
The minimum value in this range is girls.
(Round to one decimal place as needed.)
Based on the result, is 1 girl in 10 births a significantly low number of girls? Explain.
A. No, 1 girl is not a significantly low number of girls, because 1 girl is within the range of values that are not significant.
B. Yes, 1 girl is a significantly low number of girls, because 1 girl is below the range of values that are not significant.
C. Yes, 1 girl is a significantly low number of girls, because 1 girl is above the range of values that are not significant.
D. Not enough information is given.
