a. Estimate the regression equation and determine the predicted values of y b. Use the predicted values and the actual values of y to calculate the residuals c. Plot the residuals (vertical axis) against the predicted values (horizontal axis). d. Does it appear that heteroscedasticity is a problem? Explain e. Draw a histogram of the residuals. Does it appear that the errors are normally distributed? Explain. f. Use the residuals to identify possible outlier(s) Weight Price 27 12.02 28.5 12.04...

1- The regression of X on Y is not the same as the regression of Y on X. Why is this? Select one: a. Because the regression minimises the residuals of y, not the residuals of x. b. Because unlike correlation, regression assumes X causes Y. c. Because one goes through (mean x, mean y) whereas the other goes through (mean y, mean x). d. Because the F test divides MSy by MSx, not the other way round. 2- Using...

Consider the regression we know that f there is a strong linear correlation between X and Z, then it is more likely that the t-test statistics get smaller. Show and explain how. Explain what happens if t-statistics get smaller.

You are developing a simple linear regression analysis model. The simple correlation coefficient between y and x is -0.72. What do you know must be true about b1. The least squares estimator of B1? Why? In a multiple linear regression analysis with k = 3. From the t test associated with B1, you conclude that B1 = 0. When you do the f test will you reject or fail to reject the null hypothesis? Why? In a simple bilinear regression...

True or False _____I. If a negative correlation exists between X and Y, and a new data point is added whose ZX = -2.5 and ZY = 2.5, |r| will decrease. _____J. If a positive correlation exists between X and Y, and a new data point is added whose ZX = 2.5 and ZY = 2.5, |r| will decrease. _____K. In simple linear regression predicting Y from X, the unstandardized coefficient of the X variable will always equal the Pearson...
