QUESTION 3 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 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? O Two sample test of means with unknown variance (standard deviation) but assumed equal O Two sample test of means with unknown variance (standard deviation) but assumed unequal O Two sample test of means with known variance (standard deviation) Two sample test of paired means withャnknown variance (standard deviation) QUESTION 4 I have two paired samples of means and should conduct a two sample hypothesis test of paired means with unknown variance. If I instead conduct a two sample test of independent means with unknown variance, I am more likely to fail to reject the null hypothesis. True False
