Listed below are brain volumes, measured in cubic centimeters, of twins at birth. Use a 5% significance level to test the claim that there is no difference in the brain volume of the first born twin versus the second born twin. Assume that the distribution of brain volumes for newborn is normal. First Born 1005 1035 1281 1051 1034 1079 1104 1439 1029 1160 2nd Born 963 1027 1272 1079 1070 1173 1067 1347 1100 1204
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.
