External Power Supplies (EPCs) are used to power computers and appliances. Because computers and appliances are plugged in most of the time, power supplies for these devices should consume little energy when not in use (no-load). Until now, an average no-load power consumption of less than .50 watts for EPCs has been required to earn Energy Star certification. Starting next year, the Energy Star certification requirement will be reduced to .30 watts. In anticipation of this change, one manufacturer of EPCs has developed a new, lower consumption model to replace its current Energy Star certified model. The manufacturer has decided to test its no-load power consumption, shipping a sample of 30 new model EPCs to an accredited lab for testing. The manufacturer also sent a larger sample of 100 current model EPCs for comparison. The no-load consumption data for the two models are recorded below. a. First, compare the new model to the current model. Are the data paired or unpaired? What are…
