2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

Expert Solution

Step 1- Writing given data

Given that

Dr. Threpio has developed a new procedure that he believes can correct a life-threatening medical condition .

Success rate = 78% = 0.78 = P

(1 $-$ P) = (1 $-$ 0.78) = 0.22

The procedure is tried on 10 patients

Sample size (n) = 10

We know that

Binomial probability = P(X=x)= $P (X = x) =^{n} C_{x} x P^{x} x {(1 - P)}^{(n - x)}$
