What's the formula for the standard error of the difference between the estimates of the population proportions, used in a confidence interval for the difference between two proportions?

Step-by-step explanation:

The formula for the standard error of the difference between the estimates od the population proportions is:

This is expected, as the variance of a sum (or a substraction) of two random variables is equal to the sum of the variance of the two variables.

Then, the standard error (or standard deviation) is the square root of this variance.

because its not ur topic and its not for is for homework not that.

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
