WebBy default, PROC FREQ provides Wald and exact (Clopper-Pearson) confidence limits for the binomial proportion. The BINOMIAL option also produces an asymptotic Wald test that the proportion equals 0.5. You can specify a different test proportion with the P= binomial-option. The ALPHA=0.1 option specifies that %, which produces % confidence limits. http://users.stat.umn.edu/~helwig/notes/ProportionTests_slides.pdf the rock having a tea party
