You are investigating two production line methods on a factory floor. Line 1 is configured and is believed it will produce more units per hour. Line O is configured as it has been in the past and is erving as a control. You run a regression model on where Y is the output per hour over the last 50 hours for each system. The X variable is coded 1 for the new and 0 for the old systems configurations. The regression model is Y' = 45 X + 100 Is production higher or lower on the new system and by how many units? New by 100 New by 45 Old by 100 Old by 45 New by 145 Old by 145
