Answer:
Margin of Error decreases
Pvalue decreases
Power increases
Step-by-step explanation:
The margin of error decreases as sample size increases given the same level of confidence, hence, the interval gets narrower.
The margin of error = (Zcritical * σ/√n) ; where, n is the denominator, as the denomination increases, the obtained value will decrease, hence, the margin of error.
When we have a false H0, then we expect a statistical result which will reject H0, with all facts remaining unchanged , increase in sample size n, will lead to decrease in Pvalue, because a lower P value increases the significance of statistical test needed to reject H0.
The power of a fixed level test when the null hypothesis is true, higher power is required to reject the null , increasing n will increase the probability of rejecting H0, by increasing the power of a fixed level test.

<h3 /><h3>Description of the glass </h3>
A glass has the shape of a cylinder. In order to determine which glass is left, the volume of the glass has to be determined. Then what is drank would be subtracted from the volume of the glass.
<h3>
Volume of the cylinder. </h3>
Volume of a cylinder = nr^2h
- n = 22/7
- r = radius= 2.5 / 2 = 1.25
22/7 x 1.25^2 x 5 = 24.55 cubic inches
<h3>Determination of what is left </h3>
24.55 - 4.5 = 20.05 cubic inches

answer: 5.34
Step by step explanation 12.75 + 13.95=26.7
20% of 26.7 is 5.34
The answer would be D i think because if the two angles are to equal 72, and one of the angles equals 42, 72-42= 30. to find x, you’d do 30/6 which equals 5. so x=5 and the angle measure would be 30
