Suppose that you are an inspector for the Fish and Game Department and that you are given the task of determining whether to prohibit fishing along part of the Oregon coast. You will close an area to fishing if it is determined that more than 3% of fish have unacceptably high mercury levels.
a. Which of the following pairs of hypotheses would you test:
H0: p = 0.03 versus Ha: p > 0.03
or
H0: p = 0.03 versus Ha: p < 0.03
Explain the reason for your choice.
b. Would you use a significance level of 0.10 or 0.01 for your test? Explain.
