A kidney dialysis center periodically checks a sample of its equipment and performs a major recalibration if readings are sufficiently off target. Similarly, a
fabric factory periodically checks the sizes of towels coming off an assembly
line and halts production if measurements are sufficiently off target. In both
situations, we have the null hypothesis that the requirement is performing
satisfactorily. For each situation, which is the more serious concern, a Type I
or Type II error?
