At a Hepsiburada distribution facility, workers are under pressure to complete orders as quickly as possble. Completing an order means locating and collecting the ordered products and leaving them at a packaging desk. Workers are able to complete an average of 2 orders in an hour. a. What is the chance that a worker's number of completed orders per hour is more than one standard deviation of the average number of completed orders? (Round to two decimal places.) b. The new Chief Operating Officer has adopted a point-based system related to order completion. The day is split into 3- hour periods. Workers who complete a 3-hour number of orders above the average 3-hour number have a point awarded. What is the probability that a worker would receive a point at the end of a given 3-hour period? (Round to two decimal places.) E For 15 workers selected at random, what is the chance that more than 9 of them would receive a point at the end of a uon 3-bour neriod?
