![The Environmental Protection Agency (EPA) has determined that safe drinking water should contain at most 1.3 mg/liter of
copper, on average. A water supply company is testing water from a new source and collects water in small bottles at each of 30
randomly selected locations. The company performs a test at the a = 0.05 level of
Но : и 3D 1.3
На : и > 1.3
a
where u is the true mean copper content of the water from the new source.
Which type of error is more serious in this case? Justify your answer.
O A Type II error would be worse because the water would not be safe for drinking, but it would seem that it is safe.
A Type I error would be more serious because this would mean that some of the water has low levels of copper and
some has high levels of copper.
O A Type I error would be more serious because this would mean that some good water is thrown out with the bad water.
A Type II error would be more serious because this would mean that the water with more copper would be discovered](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8483a4c4-fef1-4f1e-8f46-078ffafc4d43%2F56dd7209-68c9-4ff8-bf10-761b91e7bd22%2Fvx564p_processed.png&w=3840&q=75)
