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.   x P(x) 0 0.004 1 0.013 2 0.036 3 0.115 4 0.206 5 0.238 6 0.201 7 0.116 8 0.045 9 0.013 10 0.013   The maximum value in this range is __ girls.  (round to one decimal places 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.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
