Of the 30 newly accepted juveniles into juvenile hall, half were placed in the regular program and half were placed in the vitamin and supplements program. After 12 months researchers documented the number of infractions that occurred for each of the 30 students and wanted to assess if the program worked. Group 1 (average infractions per month)• 3.2 1 0 4.7 5.3 2 1.6 4 2.8 7 4 3.1 5.7 0 1.8 Group 2 -Vitamins (average infractions per month) 0 5.2 1.2 2.1 3 1.7 0 2.9 .7 4.3 3.1 1.4 2 .9 2.6 Construct an independent samples t-test by hand.

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.
