The level of pesticides found in the blubber of whales is a measure of pollution of the oceans by runoff from land and can also be used to identify different populations of whales. A sample of 8 male minke whales in the West Greenland area of the North Atlantic found the mean concentration of the insecticide dieldrin to be x¯=354 nanograms per gram of blubber (ng/g). Suppose that the concentration in all such whales varies Normally with standard deviation σ=51 ng/g. Using software or Table C, find the 95% confidence interval to estimate the mean level of dieldrin. (Enter your answers rounded to two decimal places.)   lower bound: upper bound:
