A biologist examines 6 geological samples for lead
concentration. The mean lead concentration for the sample data is
0.714 cc/cubic meter with a standard deviation of 0.0126. Determine
the 90% confidence interval for the population mean lead
concentration. Assume the population is approximately normal.
Find the critical value that should be used in constructing the
confidence interval. Round your answer to three decimal places.
