Transcribed Image Text:Suppose that the mean of the sampling distribution for the difference in two sample proportions is 0. That is
to say p? – p2 has expectation/mean equal to 0.
This tells us that:
The two population proportions are equal to each other.
The two population proportions are both 0.
The two sample proportions are both 0.
The two sample proportions are equal to each other.
