Answer:
The 95% confidence interval is ( 27.126 , 34.674)
Step-by-step explanation:
Given
The t critical value at 0.05 level = 2.023 for the df = 39
Confidence interval = 95%
Mean
Substituting the given values we get -
Hence, the 95% confidence interval is
( 27.126 , 34.674)
check the picture below.
the line QS is just a flat-line and therefore it has 180° on either side, so the angle QPR is 57°, as you see there, and since we know the diameter is 20, that simply means the radius of the circle is 10.
D because there are two "wholes" and they are split up into 3 peices each. 2 divided by 1/3 will equal 6 because you split one "whole" into three parts and do teh same with the other.
There are several other rules that go along with the power rule.such as the products to power rule and the quotient to power rule.
