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 discharged 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°f, 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 h0: μ = 150°f versus ha: μ > 150°f. in the context of this situation, describe type i and type ii errors. what type of error would you consider more serious? explain
