Question
A researcher is studying mirex contamination in farmed salmon. He first found a95% confidence interval for the mean concentration to be 0.0834 to 0.0992 parts
A researcher is studying mirex contamination in farmed salmon. He first found a95% confidence interval for the mean concentration to be 0.0834 to 0.0992 parts per million. An environmental agency sets a limit of 0.08 ppm to be considered safe. What does the confidence interval say about the safety of the farmedsalmon?
Choose the correct answer below.
A.
The95% confidence interval lies entirely above the 0.08 ppmlimit, which is evidence that the mirex concentration is low enough to be considered safe.
B.
The95% confidence interval contains the 0.08 ppmlimit, which is evidence that the mirex concentration is too high to be considered safe.
C.
The95% confidence interval lies entirely above the 0.08 ppmlimit, which is evidence that the mirex concentration is too high to be considered safe.
D.
The95% confidence interval contains the 0.08 ppmlimit, which is evidence that the mirex concentration is low enough to be considered safe.
