We cannot construct such an interval using the normal approximation.
<h3>What is null hypothesis?</h3>
Null Hypothesis: The heart transplant procedure did not alter the survival rates of the observed patients. Alternate Hypothesis, Ha: The claim was that the patients getting a heart transplant were more likely to survive than those who did not.
<h3>What is normal distribution?</h3>
Normal distribution is the approximation for large distribution from binomial, poisson distribution etc. Moreover, the variables are discrete and few; and instead of the actual observations we are working on counts data. In the given situation it is preferred to use chi square distribution. As chi square test is used we can check whether the two groups are the same or different. Therefore, it is not possible to construct a confidence interval.

The value of the equation will be -2036.
<h3>How to calculate the equation?</h3>
It should be noted that the equation given is illustrated as:
p²m - (np + r)
m = -32
n = 2
p = -8
r = 4
In this case, we'll put the values back info the equation. This will be:
p²m - (np + r)
(-8)² × -32 - (2×-8 + 4)
-2048 - (-12)
= -2036
Therefore, the value of the equation will be -2036.

Step-by-step explanation:
Answer:
In a triangle, sum of three angles=180°
So, A+B+C=180
C=180-A-B
C=180-60-a-60+a
C=60°
Hope it helps :-)
