Constructing a Confidence Interval when the Population o is Unknown A pharmaceutical company makes tranquilizers. It is assumed that the distribution for the length of time they last is approximately normal but the population mean and standard deviation are not known. Researchers in a hospital used the drug on a random sample of nine patients. The sample mean was 2.51 hours. The sample standard deviation was 0.318. Work to construct a 95% confidence interval for the population mean by providing the following information. Useful tool: Student's t-Distribution Calculator (Include three decimal places below) а. а — b. v = c. to.025 d. EBM e. The lower bound of the Confidence Interval is f. The upper bound of the Confidence Interval is
