The Pythagorean Theorem describes an important geometric relationship between the three sides of a right triangle.
First of all, to understand the Pythagorean Theorem, you need to know about angles and triangles, and you also need to know about exponents and square roots. These things will help you understand how it works and how to solve for a missing side.
The Pythagorean Theorem
For a right triangle
with legs a and b and the hypotenuse c
+
=
The Pythagorean Theorem does not apply to all triangles.

Answer:
The 95% confidence interval is
A 95% level of confidence mean that there is 95% chance that the true population mean will be in this interval
Step-by-step explanation:
From the question we are told that
The sample size is
The mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically represented as
=>
=>
Next we obtain the critical value of from the normal distribution table , the value is
Generally the margin of error is mathematically represented as
substituting values
The 95% level of confidence interval is mathematically represented as
substituting values
The 95% level of confidence mean that there is 95% chance that the true population mean will be in this interval
