When it is operating properly, a chemical plant has a mean
Chapter 6, Problem 7E(choose chapter or problem)
When it is operating properly, a chemical plant has a mean daily production of at least 740 tons. The output is measured on a simple random sample of 60 days. The sample had a mean of 715 tons/day and a standard deviation of 24 tons/day. Let μ represent the mean daily output of the plant. An engineer tests \(H_{0}: \mu\) ≥ 740 versus \(H_{1}: \mu\) < 740.
Find the P-value. Do you believe it is plausible that the plant is operating properly or are you convinced that the plant is not operating properly? Explain your reasoning.
