Water samples are taken from water used for cooling as it is being discharged from a power plant into 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°, 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: μ = 150° versus H₂: > 150°. In the context of this situation, describe type I error. O A type I error occurs when our estimate for the mean discharge temperature is higher than the actual temperature. O A type I error occurs when we say that the plant is not in compliance when in fact it is. O A type I error occurs when our estimate for the mean discharge temperature is lower than the actual temperature. O A type I error occurs when we don't have enough information to conclude whether or not the plant is in compliance. O A type I error occurs when we say that the plant is in compliance when in fact it is not. In the context of this situation, describe type II error. O A type II error occurs when we don't have enough information to conclude whether or not the plant is in compliance. O A type II error occurs when our estimate for the mean discharge temperature is lower than the actual temperature. O A type I error occurs when we conclude that the plant is not in compliance when in fact it is. O A type II error occurs when we conclude that the plant is in compliance when in fact it is not. A type II error occurs when our estimate for the mean discharge temperature is higher than the actual temperature. Which type of error would you consider more serious? Explain. O If our focus is trying to prevent harm to the environment, then type II error is more serious because it could have an unnecessary negative impact on the power plant. O If our focus is trying to prevent harm to the environment, then type I error is more serious because it could have an unnecessary negative impact on the power plant. If our focus is trying to prevent harm to the environment, then type I error is more serious because it could result in damage that we are unaware of.
