Refer to the 4 group (packaging method)- log-bacterial growth study. In this exercise, you will use SAS/GRAPH to construct figures displaying the means and standard deviations. a. Construct a figure containing side-by-side boxplots using the INTERPOL=BOX option associated with a SYMBOL statement used with PROC GPLOT. ODS RTF file='D:\baileraj\Classes\Fall 2003\sta402\hw\hw5-prob1a.rtf’; proc gplot data=class.meat; title h=1.5 ‘Plot of log(Bacterial count) vs. packaging condition'; title2 h=1 '[boxplot is plotted for each condition]'; symbol1 interpol=box /* plots +/- 2 SD from the mean at each conc */ value=dot; plot logcount*condition; run; ODS RTF CLOSE; [pic] b. Construct a figure with the data points plotted. Superimpose the mean plus/minus 2 std. deviation segments on this plot. ODS RTF file='D:\baileraj\Classes\Fall 2003\sta402\hw\hw5-prob1b.rtf’; proc gplot data=class.meat; title h=1.5 ‘Plot of log(Bacterial count) vs. packaging condition'; title2 h=1 '[mean +/- 2SD is plotted for each condition]'; symbol1 interpol=STD2T /* plots +/- 2 SD from the mean at each conc */ /* T= add top and bottom to each 2 SD diff */ value=dot; plot logcount*condition; run; ODS RTF CLOSE; [pic] c.
