Output variable stat.Ç stat.n Description Estimated sample proportion. Size of the sample. zTest_2Prop zTest_2Prop x1,n1,x2,n2[,Hypoth] Computes a two-proportion z test. A summary of results is stored in the stat.results variable. (See page 76.) Test H0: p1 = p2, against one of the following: Hypoth > 0 for Ha: p1 > p2 Hypoth = 0 for Ha: p1 ƒ p2 (default) Hypoth < 0 for Ha: p < p0 Output variable stat.z stat.PVal stat.Ç1 stat.Ç2 stat.Ç stat.n1, stat.n2 Description Standard normal value computed for the difference of proportions. Least probability at which the null hypothesis can be rejected. First sample proportion estimate. Second sample proportion estimate. Pooled sample proportion estimate. Number of samples taken in trials 1 and 2. zTest_2Samp zTest_2Samp s1,s2 ,List1,List2[,Freq1[,Freq2[,Hypoth]]] (Data list input) zTest_2Samp s1,s2,v1,n1,v2,n2[,Hypoth] (Summary stats input) Computes a two-sample z test. A summary of results is stored in the stat.results variable. (See page 76.) Test H0: m1 = m2, against one of the following: Hypoth < 0 for Ha: m1 < m2 Hypoth = 0 for Ha: m1 ƒ m2 (default) Hypoth > 0 for Ha: m1 > m2 Output variable stat.z stat.PVal stat.x1, stat.x2 stat.sx1, stat.sx2 stat.n1, stat.n2 Description Standard normal value computed for the difference of means. Least probability at which the null hypothesis can be rejected. Sample means of the data sequences in List1 and List2. Sample standard deviations of the data sequences in List1 and List2.
