In Chapter 14 we saw data from samples of farmed salmon and examined the mirex content. The EPA sets a limit of 0.08 ppm as a maximum safe value. We performed a bootstrap on these data, drawing 10,000 resamples. Here is the resulting histogram of bootstrapped mean mirex levels: (The bootstrapped mean is 0.09134.)

a) What P-value would you assign to the hypothesis test?
b) The EPA is really only concerned with contamination abovev0.08 ppm, so perhaps a one-sided test would be more appropriate. What P-value do you now get?
