What proportion of the cells will be unacceptable

Reference no: EM131388639

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 C_p index? If we did not know the distribution of surface area, how would a capability index be found?
