Question

Water samples are taken from water used for cooling as it is
being discharged from a power plant into a river. It has been
determined that as long as the mean temperature of the dis-
charged water is at most 150°F, there will be no negative effects
on the river's ecosystem. To investigate whether the plant is in
compliance with regulations that prohibit a mean discharge
water temperature above 150°, 50 water samples will be taken
at randomly selected times and the temperature of each sample
recorded. The resulting data will be used to test the hypotheses
Ho: Le = 150° versus H: 4 > 150°. In the context of this situ-
ation, describe type I and type II errors. Which type of error
would
you consider more serious? Explain.

Answer 2

Answer:

Water samples are taken from water used for cooling when it is discharged from a power plant. If the mean temperature µ is at most 150 degrees F there will be no negative effects on the river ecosystem. ... Making this error means no remedial action will be taken and the river ecosystem will be damaged.
