Scenario: Suppose that you suspect nutrient overload in stream water, eapecially phosphorus. It is generally considered that the upper limit of phosphorus amount in natural water is 0.05 mg/L. You want to test whether the stream has a larger amount of phosphorus than the upper limit. You randomly take a water sample of size 16 from the stream. The mean phosphorus amount in the sample is 0.053 mg/L and the standard deviation is 0.008 mg/L. Perform the hypothesis test using the significance level of 0.05 by completing the following steps. 1. Null and alternative hypothesis 2. Appropriate distribution 3. A sketch of the distribution with the rejected null hypothesis area shaded in 4. The test statistic And.. 5. The p-value
