The 98% confidence interval for the intercept, coefficient of X1, and coefficient of X2 of a linear model with 2 predictors, are (18, 24), (-2,9) and (-1, 3) respectively based on 33 samples. a) What are the t-stats for X1 and X2? b) Is the coefficient of X1 statistically more significant than that of X2?
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.
