Using the z-distribution, it is found that the lower bound of the 99% confidence interval is given by:
d. 68.39%.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
In this problem, we have a 99% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 2.575.
The sample size and estimate are given by:
Hence, the lower bound is given by:
Hence the lower bound is of 68.39%, which means that option D is correct.

Well you have to change the first number in ALL of the () so
(-1,1) = (1,1)
(-2,-1) = (2,-1)
(-1,0) = (1,0)
so your answer is d <span>(1, 1), B(2, -1), C(1, 0)</span>
