A research scholar wants to know how many times per hour a certain strand of virus reproduces. The mean is found to be 8.2 reproductions and the population standard deviation is known to be 1.8. If a sample of 619 was used for the study, construct the 85 % confidence interval for the true mean number of reproductions per hour for the virus. Round your answers to one decimal place.
