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
