a. Assuming that a mercury concentration of = ppm is considered the maximum safe concentration, which of the following pairs of hypotheses would you test: H0: µ = 5 versus Ha: µ > 5 Or H0: µ = 5 versus Ha: µ < 5 Give the reasons for your choice.
b. Would you prefer a significance level of .1 or .01 for your test? Explain.
