As part of an experiential learning project, a group of ECON 227 students conducts an in-depth interview with the manager of a Starbucks store in Bloomington. From past records, the store manager tells the student researchers that during the first 30 minutes after the store is open, her store serves anywhere between 0 and 5 customers. She even goes out of her way to provide the students with the following probability distribution function for the number of customers served at her store during this time window: Customers served Probability 5 0.10 4 0.15 3 0.20 2 0.30 1 0.15 0 0.10 Find the expected value of the pdf. Find the standard deviation.
