Color-blindness is any abnormality of the color vision system that causes a person to see colors differently than most people, or to have difficulty distinguishing among certain colors (www. visionrx. com).
Color-blindness is gender-based, with the majority of sufferers being males.
Roughly 8% of white males have some form of colorblindness, while the incidence among white females is only 1%.
A random sample of 20 white males and 40 white females was chosen.
LetXbe the number of males (out of the 20) who are color-blind.
LetYbe the number of females (out of the 40) who are color-blind.
LetZbe the total number of color-blind individuals in the sample (males and females together).
Which of the following is true about the random variables X, Y, and Z?
X is binomial with n = 20 and p = .08.
Y is binomial with n = 40 and p = .01.
Z is not binomial.
All of the above are true.
Only (A) and (B) are true.
