Chapter 6: Producing Statistical Graphics in SAS 235 6.9 Exercises 1. Refer to the packaging and log-bacterial growth data. Construct three different figures that display and summarize the data. 2. Refer to the nitrofen data. Generate a plot of the nitrofen data using the square root of TOTAL as the response variable versus concentration. Superimpose the fitted quadratic model. Only use PROC SGPLOT to generate this figure (i.e., don't use PROC REG to generate fits first). 3. Refer to the nitrofen data. Fit a polynomial regression model (center the concentration variable). Use the ODS GRAPHICS statement to generate graphical summaries of this analysis. 4. Find a data set that interests you. Generate a display that best represents it using one of the SG procedures.
