The thickness of photoresist applied to wafers in semiconductor manufacturing at a particular on the wafer is uniformly distributed between 0.2032 and 0.2147 micrometers. (a) Determine the proportion of wafers that exceeds 0.2125 micrometers of photoresist thickness. (Round your answer to 3 decimal places.) (b) Determine the mean of X (in micrometers) (Round your answer to 4 decimal places.) (c) Determine the variance of X (in micrometers2) (Round your answer to 8 decimal places.)

a) P=0.191

b) E(T)=0.2090

c) V(T)= 0.00001102  

Step-by-step explanation:

The thickness T is a random variable uniformly distributed between 0.2032 and 0.2147.

a) Determine the proportion of wafers that exceeds 0.2125 micrometers of photoresist thickness.

The proportion is equal to the probability of T>0.2125.

b) Determine the mean of X (in micrometers)

The mean of a random variable with a uniform distribution is:

c) Determine the variance of X

The variance of a random variable with a uniform distribution is:

2425
