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.

I don’t bro cuz I need help to
The answer is 94 because if you add 8 more it would be 102. 14 + (8x10)
Yes she do break even because let me show you a expression now take a number line and then you start at -16 right and then you go down the number line and then this is how it go -16 -15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 and i just answer your Q there you go -16+16=0
Answer:
28ft^2
Step-by-step explanation:
you only need 2 things to find the area of the triangle, base and height. The formula for finding the area is 1/2(base x height)
if we plug the numbers we are given into the formula we find
1/2(7x8)
1/2(56)
28
we find that the area of this triangle is 28ft^2
