When conducting research on color blindness in males, a researcher forms random groups with five males in each group. The random variable is the number of males in the group who have a form of color blindness (based on data from the National Institutes of Health). 0 0.659 1 0.287 2 0.050 3 0.004 4 0.001 5 0.000 a) Determine whether a probability distribution is given. If a probability distribution is not given, identify the requirements that are not satisfied. b) Find the mean and standard deviation of the given distribution.
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.
When conducting research on color blindness in
males, a researcher forms random groups with five males in each group.
The random variable is the number of males in the group who have a form
of color blindness (based on data from the National Institutes of Health).
