K1.14 Bernoulli Trials For a 100 question multiple choice exam with 4 options per question, a student randomly guesses. Each guess is a Bernoulli trial with success probability p = 1/4. Thus, the number of correct answers S10o has a binomial distribution with 1 3 5 13 mean np = 100 . = 25 and standard deviation vnp(1 - p) =1/100 13~ 4 4 4 2 3 A student has 7 correct answers. This has a z-score 7-25 54 Z ~
