Question: In solar cells, the exposed surface area is the characteristic of interest. The tolerances on the length and width of the cells are 4

In solar cells, the exposed surface area is the characteristic of interest. The tolerances on the length and width of the cells are 4 ± 0.06 cm and 5 ± 0.09 cm, respectively. Assuming these dimensions to be independent of each other and each normally distributed with a capability ratio of 1, what are the natural tolerance limits on surface area? If the design calls for specifications on the surface area to be 20 ±0.4, what proportion of the cells will be unacceptable assuming normality? What is the Cp index? If we did not know the distribution of surface area, how would a capability index be found?
