Assume that a procedure yields a binomial distribution with n trials and the probability of success for onetrial is p. Use the given values of n and p to find the mean u and standard deviation o. Also, use the rangerule of thumb to find the minimum usual value u- 20 and the maximum usual value u+ 20.Guessing on ACT Random guesses are made for the 60 multiple-choice questions on the math portion of theACT test, so n = 60 and p = 1/5 (because each question has possible answers of a, b, c, d, e, and only one ofthem is correct). Round to 1 decimal.Mean =Standard Deviation=Minimum Usual Value -Maximum Usual Value=
