A cоmpаny clаims thаt the pоtency оf a particular drug product is effective for 2 years after production. To verify this claim, the company officials collected a random sample of 10 bottles of the product from the production line and stored them in a regulated environment for a period of 2 years. The gold standard of the product potency is 10 GM. Using the data, they test H0: the true mean potency of the drug after 2 years is 10 GM H1: the true mean potency of the drug after 2 years is different from 10 GM Fill in the blanks by selecting from the dropdown menu. If the test determines that the true mean potency of the drug after 2 years is 10 GM, when it is actually different, then this is a [fill1] error. If the test determines that the true mean potency of the drug after 2 years is different from 10 GM, when it actually is 10 GM, then this is a [fill2] error. The [fill3] of the test is the probability that the test determines that the true mean potency of the drug after 2 years is different from 10 GM, when it is in fact different. The [fill4] of the test is the probability that the test incorrectly determines that the true mean potency of the drug after 2 years is different from 10 GM.
