The department of natural resources reports that a fish is unsafe to eat if the polychlorinated biphenyl (PCB) concentration exceeds 5 ppb. PCB is normally distributed. A random sample of 10 fish taken from a local lake results in the data listed below. Does the data suggest that the fish from this lake should not be eaten? Base your alpha on a 95% confidence interval. (write in complete context, include the possible error and it’s consequences)
