A researcher is studying mirex contamination in farmed salmon. He first found a 95% confidence interval for the mean concentration to be 0.0834 to 0.0992 parts per million. Later he rejected the null hypothesis that the mean did not exceed theEPA's recommended safe level of 0.08 ppm based on a P-value of 0.0027. Explain how these two results are consistent, discussing the confidence level, the P-value, and the decision. A. The 95% confidence interval lies entirely above the 0.08 ppm limit, which is consistent with failing to reject the nu hypothesis. The researcher used an upper-tail test, so the P-value should be smaller than 0.5 0.95 0.025, which it was B. The 95% confidence interval lies entirely above the 0.08 ppm limit, which is consistent with rejecting the null hypothesis. The researcher used an upper-tail test, so the P-value should be smaller than 0.501 -0.95) -0.025, which it was. C. The 95% confidence interval lies entirely above the 0.08 ppm limit, which is consistent with failing to reject the null hypothesis. The researcher used a two-ta test, so the P-walue should be smaller than (1-0.95) 0.05, which it was D. The 95% confidence interval lies entirely above the 0.08 ppm limi it, which is consistent with rejecting the nu hypothesis. The researcher used a two-ta test, so the P-value should be smaller than (1-0.95) 0.05, which it was.
