A wildlife researcher wants to know how many fish in a lake have been tagged by previous researchers. Use a 90% confidence interval to estimate the minimum number of fish that need to be caught and examined in order to yield results that are normally distributed with a standard deviation of 3 and a margin of error of ±0.6 fish with tags. (Recall the following z-scores for each level of confidence: 90% = 1.645, 95% = 1.960, and 99% = 2.575.) %3D
