You do a psychophysical experiment on the consistency of appreciation of aesthetic beauty by humans. you pick 2 observers and ask each of them to make 100 aesthetic judgments of a painting. when estimating mean and variability of these judgments, you have this many degrees of freedom
a. 0
b. 199
c. 200
d. 1
e. 100

correct option is B. 199

Step-by-step explanation:

given data

pick observers = 2

make =  100 aesthetic judgments

to find out

degrees of freedom

solution

we know that the degrees of freedom is express here as

degrees of freedom =  2 n - 1      1

here we know n is 100 given

so put here value we get

degrees of freedom =  2 n - 1

degrees of freedom =  2×100 - 1

degrees of freedom = 199

so correct option is B. 199

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
