Drugs A was prescribe far a random sample of 12 patients complaining of insomnia.an independent random sample of 16 patients with the same complain received drug B. The number of hours sleep during the second night after the treatment began as follows: A 3.5 5.7 3.4 6.9 17.8 3.8 3.0 6.4 3.6 6.9 5.7 3.8 B 4.5 11.7 10.8 4.5 6.3 3.8 6.2 6.6 7.1 6.4 4.5 5.1 3.2 4.5 3.0 4.5 Which sample have more variation.is there any outlier in sample B. Also discuss symmetry and skewness about the sample A.
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.
