Researchers with the state Department of Natural Resources (DNR) wish to estimate the mean flow rate of water through a stream. From previous research conducted on similar streams, they know that the variance of flow rate is 27,556 gpm2. If the DNR researchers wish to create an interval that they are 99% confident will contain the mean flow rate with bound on the error of estimation of 40 gpm, how many flow samples do they need
