Assume we are interested in determining whether the proportion of voters planning to vote for candidate C (pC) is significantly less than the proportion of voters planning to vote for candidate B (pB). The correct null hypothesis for testing the above is
|
Ho: pC – pB > 0 |
|
Ho: pC – pB < 0 |
|
Ho: pC – pB < 0 |
|
Ho: pC – pB > 0 |
