Problem 3E

A dry etch process is used to etch silicon dioxide (Si02) off of silicon wafers. An engineer wishes to study the uniformity of the etching across the surface of the wafer. A total of 10 wafers are sampled after etching, and the etch rates (in Å/min) are measured -at two different sites, one near the center of the wafer,and one near the edge. The results are presented in the following table.Can you conclude that the mean amount of corrosion

Can you conclude that the etch rates differ between Code the center and the edge?
