You find that the average income for college students is $20,000 +/- $200 (with a confidence level of 95%). Indicate the CORRECT interpretation(s) of this finding below (you may select more than one).

a. I am 95% certain that the average income for college students is $20,000.
b. If the same sampling and statistical procedures are conducted 100 times the true population mean will be encompassed between $19,800 and $20,200 (and 5 times it will not).
c.5% of college students make less than $19,800.
d.95% of college students make more than $20,200.
e. I am 95% sure that the average income of college students is between $19,800 and $20,200.

Drag and drop the answers into the boxes to complete this informal argument explaining how to derive the formula for the volume of a cone. since the volume of a cone is part of the volume of a cylinder with the same base and height, find the volume of a cylinder first. the base of a cylinder is a circle. the area of the base of a cylinder is , where r represents the radius. the volume of a cylinder can be described as slices of the base stacked upon each other. so, the volume of the cylinder can be found by multiplying the area of the circle by the height h of the cylinder. the volume of a cone is of the volume of a cylinder. therefore, the formula for the volume of a cone is 1/3 1/2 1/3πr^2h 1/2πr^2h πr^2h πr^2

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?
