A biologist examines 15 sedimentary samples for lead concentration. The mean lead concentration for the sample data is 0.511 cc/cubic meter with a standard deviation of 0.0598. Determine the 98% confidence interval for the population mean lead concentration. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
