A manufacturing firm produces microchips where the defect rate follows a Poisson process with an average of defects per wafer. If the number of defects per wafer is observed and we introduce a quality control mechanism that replaces a fraction of defective chips with non-defective ones, resulting in a new random variable . How does the variance of compare to the variance of ?
