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.
- z is the critical value.
- n is the sample size.
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.

Answer:
The given triangle is NOT A RIGHT ANGLED TRIANGLE.
Step-by-step explanation:
Here, the three given sides of the triangle are:
8 units, 10 units and 12 units
Now, for any triangle to be a right angle:
by the PYTHAGORAS THEOREM:
The longest of all sides id the hypotenuse.
⇒ H = 12 units
Let us assume, B = 8 units, P = 10 units
Now, here checking the condition:
Hence, the given triangle is NOT A RIGHT ANGLED TRIANGLE.
