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

(a) If the plant is not exceeding the limit, but actually μ =

1000, there is only a 5% chance that we will conclude that they are exceeding the limit.

(b) If the 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 H0 were true.

(d) If we reject H0, the probability that it is actually true is 0.05.

(e) All of the above.
