(1). Linear relationship between 2 variables. Note: Correlation can only reveal any linear relationship is associated with 2 random Variables, It can't detect Othe relationshin such as quadratie, Cubic or any other polynomial relationship (2) Categorical Coption is correct) Reason: chi square statistie is used to detect whether the distribuition Of Categorical variables are different or not. (3) option b is the correct answer, you highlight You highlighted option C, which is wrong ERA Reason : X test is used to test Independence, Association, Goodness of fit. You selected option C, testing for several means is done by ANOVA CE test)
