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.
Pleаse nоte thаt this questiоn cоnsists of three pаrts. Show all your work/explanation. Just giving the answer without adequate work/explanation may result in zero for the question. A customer protection agency conducts a study to estimate the true mean delivery time by a private courier company within a major city. They randomly select 36 deliveries and record their delivery times. For this sample the mean was 174 minutes with standard deviation 45 minutes. Find a 95% confidence interval for the true average delivery time. Interpret the confidence interval above in the context of the problem. The private courier company claimed that on average their delivery time is within 2.5 hours. Based on the interval in part 1, was the company's claim correct? Explain.
