Answer:
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.
Answer:
Step-by-step explanation:
(4+4)/(0-2)= 8/-2 = -4
y + 4 = -4(x - 2)
y + 4 = -4x + 8
y = -4x + 4

Step-by-step explanation:
Answer:
y+6=(x-6)
Step-by-step explanation:
Slope intercept form is y-y1=m(x-x1).
So in this case, the y1 value is -6, the x1 value is 6, and the slope (m) value is .
