HypZ1mean The hypothesis test HypZ1mean is a one-sample Z-test for
comparing means.:
HypZ1mean(SampMean, SampSize,
NullPopMean, PopStdDev, SigLevel, Mode)
• Mode: Specifies how to calculate the statistic:
1 = Less than
2 = Greater than
3 = Not equal
HYPZ2mean The hypothesis test HypZ2mean is a two-sample Z-test for
comparing means.
HypZ2mean(SampMean, SampMean2,
SampSize,SampSize2, PopStdDev,
PopStdDev2,SigLevel, Mode)
• Mode: Specifies how to calculate the statistic:
– 1 = Less than
– 2 = Greater than
– 3 = Not equal
HypZ1prop The hypothesis test HypZ1prop is a one-proportion Z-test.
HypZ1prop(SuccCount, SampSize,
NullPopProp, SigLevel, Mode)
• Mode: Specifies how to calculate the statistic:
– 1 = Less than
– 2 = Greater than
– 3 = Not equal
HypZ2prop The hypothesis test HypZ2prop is a two-proportion Z-test for
comparing means.
HypZ2prop(SuccCount1, SuccCount2,
SampSize1, SampSize2, SigLevel, Mode)
