Menu name

Z–Test: 1P

 

 

On the basis of statistics from a single sample, this test

 

measures the strength of the evidence for a selected

 

hypothesis against the null hypothesis. The null hypothesis is

 

that the proportion of successes in the two populations is

 

equal. H0π = π0

 

 

You select one of the following alternative hypotheses against

 

which to test the null hypothesis:

 

 

H1:π < π0

 

 

H1:π > π0

 

 

H1:π ≠ π0
