SAS code please.

Two cholesterol-lowing medications (statins) and a placebo were given to each of 10 volunteers with total cholesterol; readings of 240 or higher. After 6 weeks, the flowing total cholesterol values were recorded:

Stain A: 220 190 180 185 210 170 178 200 177 189

Stain B: 160 168 178 200 172 155 159 167 185 199

Placebo: 240 220 246 244 198 238 277 255 190 188

(a) Run a one-way ANOVA followed by a Duncan’s multiple range test.

(b) Create a contrast to compare Placebo against the mean of Stain A and Stain B.
