Assume that a sample is used to estimate a population mean μ. Find the 99.5% confidence interval for a sample of size 39 with a mean of 66.4 and a standard deviation of 9.3. a. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place. Confidence interval = b. Express the same answer as a tri-linear inequality one decimal place. << c. Express the same answer using the point estimate and margin of error. Give your answers to one place. x = 66.4
