Many cardiac patients wear an implanted pacemaker to control their heartbeat. A plastic connector module mounts on the top of the pacemaker. Assuming a standard deviation of 0.0012 inch and an approximately normal distribution, find a 90% confidence interval for the mean of the depths of all connector modules made by a certain manufacturing company. A random sample of 85 modules has an average depth of 0.309 inch. The confidence interval is _______ < μ <___________
