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
