Do not round.) Find the probability of getting 6 or more girls in 8 births. (Type an integer or a decimal. Do not round.) Which probability is relevant for determining whether 6 is a significantly high number of girls in 8 births: the result from part (a) or part (b)? A. The result from part a, since it is the exact probability being asked. B. The result from part a, since it less than the probability of the given or more extreme result. C. The result from part b, since it is the probability of the given or more extreme result. D. The result from part b, since it is the complement of the result of part a. Is 6 a significantly high number of girls in 8 births? Why or why not? Use 0.05 as the threshold for a significant event. A. No, since the appropriate probability is greater than 0.05, it is not a significantly high number. B. Yes, since the appropriate probability is less than 0.05, it is a significantly high number. C. Yes, since the appropriate probability is greater than 0.05, it is a significantly high number. D. No, since the appropriate probability is less than 0.05, it is not a significantly high number.
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.
