A contingency table test was conducted on the independence of two ways of classi cation of the population of interest. The table had four rows and four columns. The sample size was equal to 350. What is the number of degrees of freedom for the sampling distribution of the test statistic? a) 4 b) 6 c) 9 d) 12 e) 346
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
A
