Please assist me, I am struggling

Formal Assessment 36 points Please show work. Q1. What is value of the slope of the regression line if Sy = 10 units and S): = 2 units and r = .732? Q2. Why is it not possible to calculate a regression correlation coefficient between X = weight and Y = gender? Why is it possible to calculate a regression correlation coefficient between X = weight and Y = height? QB. A regression was performed and the regression line is ln(Yhat) = |n()(} + 0.124. What is Yhat (Y predicted) for X = 3? What is the value of the residual if the ordered pair (3, 1) is in the original set of data? 0.4. A scatter plot of the data indicates a strong, positive, linear relationship between Educational Attainment (Years of Schooling) by age 30 (X) and Income (5) at age 30 (Y). You perform the regression and create the residual plot. What variable/measure is on the X-axis of this plot? What variable or measure is on the Y-axis ofthis plot? What do you expect to find when you examine the residual plot? Q5. The equation of the regression line for Q4 is Y-hat = 4200X 1500. Interpret the slope of the regression line. What is Yhat f0r X = 16 years (college graduate)? Q6. Assume that r = .90 for Q4 and Q5. Interpret RAZ in the context of this question. Page1l1\\+
