6.52. We analyze whether the true mean discharge of wastcwatcr per hour from an industrial plant exceeds the company claim of 1000 gallons. For the decision in the one-sided test using a = 0.05:

(a) Ifthe plantis not exceeding the limit, but actually p - 1000, there is only a 5% chance that we will conclude that they are exceeding the limit.

(b) Ifthe plant is exceeding the limit, there is only a 5% chance that we will conclude that they are not exceeding the limit.

(c) The probability that the sample mean equals exactly the observed value would equal 0.05 if Hq were true.

(d) If we reject Ho, the probability that it is actually true is 0.05.

(e) All of the above.
