Answer:
The claim is NOT tenable.
Explanation:
For the claim to be tenable, the maximum defective products should not be more than 24 (600×4% = 24).
The current random sample had 35 defective products which makes the claim NOT tenable and thus, the manufacturer claims are not true.

No, the claim is not tenable.
- The manufacturer claims that there is only 4% defective product supplied by him.
- This statement of the manufacturer is contradicted by the data given that out of 600 samples of the product, 35 are found defective.
- Since, 4% of 600 is equal to 24, there should be only 24 defective products in the sample but there are more than 24 defective products in the given sample.
- Hence, the claim is not tenable.
