A production facility has a constant flow of truck drivers that pickup products to deliver to customers. Recently, they have installed a new automatic gate system. Occasionally, truck drivers have issues either entering or exiting the facility using the automatic gate system. Over the course of one week, the production facility randomly selected 8 truck drivers. The random sample showed the 8 truck drivers had an average of 4.5 (with a standard deviation of 3.3) issues with entry into the facility and an average of 6.6 (with a standard deviation of 2.0) issues with exit from the facility. The production facility would like to know if the new automatic gate system has MORE issues with exiting the facility than entering it. What test should be used
