In a quality control study, a manufacturing plant produces batches of 100 products each, and we count the number of defective products in each batch to assess the plant’s reliability. Define the random variable
X
to model this situation.
Choose the one correct answer:
The random variable
X
represents the total number of products in each batch, which is fixed at 100.
The random variable
X
represents the plant’s reliability, recorded as a binary outcome where 1 indicates a "reliable" batch (no defects) and 0 indicates an "unreliable" batch (at least one defect).
The random variable
X
represents the number of defective products in a batch of 100.
