21:17 Q AA E .* ... 25.5 20 neters, and sketch the binomial distribution. For a true/false quiz, cor- uesses are equally likely, p = q =. With pn and qn both greater than 10, the ion is appropriate and will have a mean and a standard deviation as follows: µ = pn = 0.5(40) = 20 o = Vnpg = V10 = 3.16 ows the distribution. We are looking for the probability of getting X = 26 or crect, so we will use the lower real limit for 26, which is 25.5. = 25.5 is calculated as follows: X - pn z = Vnpq 25.5 – 20 = +1.74 3.16 ne unit normal table, the proportion we want is 0.0409. Thus, the probabil- ast 26 questions right just by guessing is p(X > 26) = 0.0409 (or 4.09%) 4. A psychology class consists of 28 males and 52 females.
