In your bid to be elected class representative, you have your election committee survey five randomly chosen students in your class and ask them to rank you on a scale of 0-10. your rankings are 3, 2, 8, 4, 3.

(a) find the sample mean and standard deviation. (round your answers to two decimal places.)
(b) assuming the sample mean and standard deviation are indicative of the class as a whole, in what range does the empirical rule predict that approximately 68% of the class will rank you?
