Reference no: EM132858314

Water samples were obtained at 35 randomly-selected sites in the Lower Willamette River, and the concentration of mercury (mg/kg--miligrams per kilogram) were recorded. The sample mean mercury concentration is 0.02 mg/kg. The population standard deviation can be assumed to be 0.006.

The margin of error for a 95% confidence interval for the true mean mercury concentration in the Lower Willamette River is (rounded to five decimal digits) is
