Sometimes it is desirable to assign numerical “code" values to experimental responses that are not basically of numerical type. For example, in testing the color preferences of experimental subjects, suppose that the colors blue, green, and red occur with probabilities

Transcribed Image Text:1/4, 1/4, and 1/2, respectively. A different integer value is assigned to each color, and this
corresponds to a random variable X that can take on one of these three integer values.
(a) Can f(x) = (1/4) *\(1/2)' - 1*1 for x = -1, 1, 0 be uscd as a pdf for this experiment?
(b) Can f(x) = ( 1/2)*
for x = 0, 1, 2 be used?
