Description
Running Head: MONTE CARLO ASSIGNMENT sim1 n(mean,sd)samplesize Given these population conditions, the test appears to be ROBUST because actual alpha (507/10000=0.0507) falls within a fairly stringent 10% of the desired nominal alpha (that is, between 0.0450 and 0.0550). 507-rejections 0.05070- actual alpha p=.o5 GET DATA /TYPE=TXT /FILE="C:\Documents and Settings\mackug.CSAHS-UGLS- TEST\Desktop\MC2G_meanssim1.dat" /DELCASE=LINE /DELIMITERS="," /ARRANGEMENT=DELIMITED /FIRSTCASE=2 /IMPORTCASE=ALL /VARIABLES= sample F3.0 mean1 F8.5 mean2 F8.5 sd1 F7.5 sd2 F7.5 diff F8.5 sediff F7.5 n1 F2.0 n2 F2.0.
