Step-by-step explanation:
If we extract a sample of size n from a normal population and we want to estimate the population mean then the confidence interval for the mean will be:
Where
Where is an estimator for the mean μ.
n is the sample size and s is its standard deviation.
is the level of significance
= 1-Confidence Level
Then
Then the 99% confidence interval for the population mean is
Check the picture below.
∡a has a vertical angle sibling of 40°, and vertical angles are always congruent.
∡b is the 3rd angle in a triangle, the other two are 40° and 90°, recall all interior angles in a triangle add up to 180°.
∡c is a linear angle, namely an angle on the same flat-line as another, and linear angles always add up to 180°.
