Test for one proportion
The Test for one proportion in the Tests menu can be used to test the hypothesis that an observed proportion is equal to a pre-specified proportion.
This test is not performed on data in the spreadsheet, but on statistics you enter in a dialog box.
When all data have been entered click the Test button.
The program displays:
If the P-value is less than 0.05, the hypothesis that the observed proportion is equal to the pre-specified proportion value is rejected, and the alternative hypothesis that there is a significant difference between the two proportions can be accepted.
In the Comment input field you can enter a comment or conclusion that will be included on the printed report.
