Several cell biology students are unprepared for a surprise true/false test with 28 questions, and all of their answers are guesses. Find the mean for the number of correct answers for such students. (Round answer to one decimal place.) P= Find the standard deviation for the number of correct answers for such students. (Round answer to two decimal places.) σ= Give the range for the usual number of correct answers. (Enter answer as an interval using square-brackets only with whole numbers.) usual values= Would it be unusual for a student to pass by guessing and getting at least 17 correct answers? O yes, it would be unusual O no, it would not be unusual
