i.e. sample proportion p=
Std error of p =
For 90% Z crtiical = 1.645
Hence margin of error = 1.645 * std error = 0.0285
Confidence interval 90%
= proportion ±margin of error

Answer
Step by step explanation
Let the points be A and B
A ( 5 , 1 ) ⇒ ( x₁ , y₁ )
B ( -3 , -5 )⇒ ( x₂ , y₂ )
Now, let's find the distance between theses two points:
Distance =
Plug the values
Calculate
Evaluate the power
Add the numbers
Write the number in exponential form with a base of 10
Reduce the index of the radical and exponent with 2
-------------------------------------------------------------------------------
The distance formula is used to determine the distance ( d ) between two points. If the co-ordinates of the two points are ( x₁ , y₁) and ( x₂ , y₂ ) , the distance equals the square root of x₂ - x₁ squared + y₂ - y₁ squared.
