Question 18 1 pts Assume that a procedure yields a binomial distribution with n trials and the probability of success for one trial is p. Use the given values of n and p to find the mean y and standard deviation o. Also, use the range rule of thumb to find the minimum usual value p - 20 and the maximum usual value 4 + 20. Guessing on ACT Random guesses are made for the 60 multiple-choice questions on the math portion of the ACT test, so n = 60 and p = 1/5 (because each question has possible answers of a, b, c, d, e, and only one of them is correct). Round to 1 decimal. Mean = Standard Deviation Minimum Usual Value - Maximum Usual Value
