Answer:
Step-by-step explanation:
For this case we have a confidence interval given as a percent:
If we express this in terms of fraction we have this:
We know that the confidence interval for the true proportion is given by:
And thats equivalent to:
We can estimate the estimated proportion like this:
And the margin of error can be estimaed using the fact that the confidence interval is symmetrical
And then the confidence interval in the form desired is:
Answer:
Step-by-step explanation:
The equation of a line
y = mx + c
y - intercept point y
m - slope of the line
x - intercept point x.
c - intercept of the line
Step 1: find the slope
m = y2 - y1 / x2 - x1
Given two points
( -7 , -7) ( -7 , 4)
x1 = -7
y1 = -7
x2 = -7
y2 = 4
Insert the values into the equation
m = 4 - (-7) / -7 -(-7)
m = 4 + 7 / -7 + 7
m = 11/ 0
Step 2: sub any of the two points given into the equation
y= mx + c
y = 11/0x + c
(-7 ,4 )
x = -7
y = 4
4 = 11/0(-7) + c
4 = -77/0 +c
-77/0 is math error which means that the points are not correct
