An engineer measured brightness values (in foot-lambert) of six display samples (3 samples of 1.0 mm thickness and 3 samples of 1.5 mm thickness) provided by each of three display suppliers. The measured values are provided below. Display Supplier Glass Thickness A B C 1.0mm 280 300 290 1.0mm 290 310 285 1.0mm 285 295 290 1.5mm 230 260 220 1.5mm 235 240 225 1.5mm 240 235 230 Given that brightness specification is > 270, what combination of Glass Thickness and Supplier should be selected to meet the specification with minimum variability
