1. Multiple choice questions each have 6 possible answers, one of which is correct. Assume that you guess the answers to 5 such questions. What is the probability of getting exactly one correct answer when 5 guesses are made?
2. Pretty Betty has a share of 28. 28% of households were tuned to Pretty Betty. Assume an advertiser verifies 28% survey with 15 households. Find probability that at most one household is tuned to Pretty Betty. P(at most one).
3. Assume that a procedure yields a binomial distribution with n=405 trials and the probability of success for one trial is p=0.59. Use the range rule of thumb to find minimum usual value of mean -2 standard deviations and the maximum usual value of the mean + 2 standard deviations.
4. Several anthropologist students were unprepared for a true/false quiz with 15 questions. All answers were guesses. Give the range for the usual number of correct answers.
