Use the data set here for this problem.   a) What is the maximum value for X2? [a_maxX2]. b) What is the standard deviation of Y? [b_sd]. c) What is the correlation between Y and X1? [c_pt3294]. d) Construct scatterplots of the X variables against Y.  T/F: there appears to be a positive relationship between Y and X3. [d_TRUE]. e) Regress Y on X1, X2 and X3.  What is the R2 for this regression? [e_r2]. f) Examine the default residual plots in R.  Are there any influential observations? [f_no]. g) Obtain the standardized residuals.  Conduct a test of the assumption that these residuals are normally distributed. Use the test covered in this class.   What is the test statistic for this test? [g_SWstat]. h) Based on this test do you conclude that the errors are approximately normally distributed or that they are not normally distributed? [h_normal]. i) Perform a Box-Cox analysis.  Which value for lambda is most appropriate? [i_lambda] j)  Apply the transformation and rerun the regression.  That is, run a new regression using the transformed variable based on part (i).  What is the estimated coefficient on X1 in this regression? [j_pt5043]. k) For the regression in part (j) with the transformed variable, test the hypothesis 

When the errors are correlated, a possible remedial measure is to use either the Cochrane-Orcutt procedure or the Paris-Winsten procedure.

To draw a circle by specifying three known points on the circle, invoke the __________________ tool.

Outline the steps from creating to printing a new MicroStation drawing. (Hint: Think about settings, levels, objects, dimensioning, printing, etc.)

Match the following dimensioning terms to the best answers:

In MicroStation, you can change the working units after you start drawing and the file will update automatically.

To setup Working Units, we need to select Design file from the Settings menu.
