The 95% confidence interval for the population standard deviation will be,
simplifying the equation, we get
The 95% confidence interval exists (9.887, 21.288).
<h3>What is the 95% of confidence interval?</h3>
A random sample of 15 men exists selected. The mean weight exists at $165.2 pounds and the standard deviation exists at $13.5 pounds. The population exists normally distributed.
So,
where n exists the sample size, exists the sample size
s exists the sample standard deviation.
The degrees of freedom will be n - 1 i.e.15 - 1 = 14.
For a 95% confidence interval, the level of significance will be .
The 95% confidence interval for the population standard deviation will be,
substitute the values in the above equation, we get
simplifying the above equation, we get
The 95% confidence interval exists (9.887, 21.288).

Answer: x= 98°
Step-by-step explanation:
Concept:
Here, we need to know the concept of the "Exterior Angle theorem"
The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two opposite angles of the triangle.
If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
x = 53 + 45 = 98°
