A biologist wants to understand the average mercury concentration of fish in western Oregon lakes. She chooses a simple random sample of lakes and collects 110 fish altogether. The average mercury content in the fish, measured in parts per million (ppm), is found to be 0.15. Assuming the standard deviation of mercury content in all fish is σ=0.06, find a 95% confidence interval for the mercury content of fish in western Oregon lakes.
