random sample of residents from various income brackets were asked their operating on tac reform for the country of Guyana. The data so gathered were analyzed by a statistician and the results he obtained using MINITAB are shown below: Low. Middle. Might. Total For. 26 75 14 115 (30.67) (51.11) (33.22) Against. 60 95 105 260 (69.33) (115.56) (**) Neutral. 34 30 11 75 (20) (33.33) (21.67) Total. * 200 130 450 Child's = 0.71+ 11.17+ 11.12+ ***+ 3.66+ 11.89+ 9.8 0.33+ 5.25=55.2 DF =??, PM value = ???

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.
