Using the z-distribution, it is found that the 95% confidence interval is (0.46, 0.526), and it does not provide strong evidence against that belief.
<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 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
We have that a random sample of 864 births in a state included 426 boys, hence the parameters are given by:

Then, the bounds of the interval are given by:


The 95% confidence interval estimate of the proportion of boys in all births is (0.46, 0.526). Since the interval contains 0.506, it does not provide strong evidence against that belief.

I think your answer is going to be 23
but how can we determine if there is no pic
The correct answer is 48%
There are 10 even numbers from 1 to 21.
That makes the probability of an even number 10 out 21.
10 / 21 x 100 = 48%
The area of regular hexagon is 166.27688 inch².
<h3>What is area?</h3>
The area is the amount of space within the perimeter of a 2D shape.
Given:
side = 8 inch
Using
Area of regular hexagon = 3 √3/2 * a²
= 3 √3/2 * 8*8
=96√3
= 166.27688 inch²
