Answer 1

Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

Lets check the data for the specifications mentioned in the question.

The specifications says that the value of viscosity should be between 12.5 and 17.5.

Every value is within these limits of 12.5 and 17.5.

Therefore, 100% of the values are within specifications.
