You are the quality control manager at a steel mill making sheet metal. The thickness of the sheet metal being pressed is measured at the rollers with a LVDT. A set of LVDT voltage readings are tabulated in the data below. The LVDT used for measurements is a RDP Electrosense ACT1000A, powered at 7 VAC. Use the information to determine the average thickness of each sheet, which are outside tolerance and the average thickness of the "good" sheets. What gauge sheet metal is being produced?
