Researchers purchased whole farmed salmon at random from 51 farms in eight
regions in six countries (see For Example: “Finding a confidence interval for the mean
contaminant levels in fish”). The histogram shows the concentrations of the insecticide
Mirex in the 150 samples of farmed salmon we examined previously:

QUESTION:

Are the assumptions and conditions for making a confidence interval
for the mean Mirex concentration satisfied?
