g if we want to calculate a confidence interval of the difference of two proportions what is the standard error (do not pool for this answer)

The standard error is , in which are the proportions and are the sample sizes.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.

In which

z is the z-score that has a p-value of .

The standard error is:

For the difference of proportions:

For proportion 1, the standard error is:

For proportion 2, the standard error is:

For the difference:

The standard error is the square root of the sum of the squares of each separate standard error. So

The standard error is , in which are the proportions and are the sample sizes.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
