Here are the scatter plots for two sets of bivariate data with the same response variable. The first compares the variables x & y. The second compares the variables w & y 00⁰0 889 Which explanatory variable has a stronger relationship with the response variable y? The first variable (x) has a stronger relationship with the response variable y. The second variable (w) has a stronger relationship with the response variable y.

Q6 Given a data set where the response variable is normalized ( centered ) and it is know that the correlation between the individual predictor variable & response variable is, r 0.9. And, it is found that S,-10 and X=100. (i) Find B= a. Write the formula for B= (ii) Find B= (iii) (iv) Find the value the predictor, which yields the response variable to be 1 X Q7 There are several assumptions which are needed to be verified prior to using a univariate regression model and/or doing any traditional model analysis ( e.g. need to verify these assumptions prior to doing the actual regression or F/T tests etc ). Write down the two most essential mathematical assumptions needed by explaining them in a brief written statement (i) 1" = (ii) 2* = answer both questions plese
