Context: A biomedical research laboratory is evaluating the effectiveness of a new medication in reducing blood glucose levels. Based on previous studies, it is known that the standard deviation of glucose levels in untreated patients is 15 mg/dL. It is believed that the new drug can alter the average blood glucose level, which in an untreated population is 120 mg/dL. Data: After administering the drug to a random sample of 30 patients, an average of 110 mg/dL in glucose levels is observed. Task: Find the 95% confidence interval for the average blood glucose level "u" after treatment.
