17)
A batch of 1,000 parts has been produced and a decision is needed whether or
not to 100% inspect the batch. Past history with this part suggests that the
fraction defect rate is around 0.02. Inspection cost per part is $0.15. If the batch
is passed on for subsequent processing, the damage cost for each defective unit
in the batch is $9.00. Determine the batch cost if no inspection is performed.
$180

The pixel count of a digital camera that uses a CCD image sensor is 1600 ×
1200. Each pixel is converted from an analog voltage to the corresponding digital
signal by an analog-to-digital converter. Each conversion takes 0.015 μ-sec
(0.015 × 10-6 sec). The time it will take to collect and convert the image data for
one frame is 0.0288 sec. Can this be done 30 times/sec? Yes, less than
conversion
