Suppose X, is a numerical variable and X, is a dummy variable with two categories and the regression equation for a sample of n= 22 is Y, =7-6X, - 3X- a. Interpret the regression coefficient associated with variable x,. b. Interpret the regression coefficient associated with variable X,. c. Suppose that the tsTAT test statistic for testing the contribution of variable X, is - 3.17. At the 0. O level of significance, is there evidence that variable X, makes a significant contribution to the model? a. Interpret the regression coefficient associated with variable X, Holding constant the effect of X,, for each increase of one unit in X,, the predicted mean value of Y decreases by a positive change of 6 unit(s). b. Interpret the regression coefficient associated with variable X,. Holding constant the value of X,, changing the value of X, from 0 to 1 is estimated to decrease the predicted mean value of Y by a positive change of 3 unit(s). c. Determine the null and alternative hypotheses. Họ: B2 - 0 H: 2 * 0 State the test statistic. tSTAT = (Round to two decimal places as needed.)

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.
