The active ingredient in antiseptic liquid bandages is 8-hydroxyquinoline (8h) . This chemical can be harmful when it is ingested through simple skin contact, by swallowing, or inhalation. Suppose the list of ingredients on a 3M Nexcare liquid bandage indicates that the volume of 8h is 1%. A random sample of eight bottles of this product was obtained, and each was analyzed to obtain the volume of 8h. The sample mean was x = 1.025%. Assume the underlying population is normal and o - 0.04. Is there evidence to suggest that the true mean percentage of 8h is different from 1%? Use a = 0.01. Determine the test statistic. Round your answer to three decimal places. @ Macmillan Learning 1.77 test statistic: Incorrect three decimal places
