- The FDA regulates that fish that is consumed is allowed to contain 1 mg/kg of mercury. In Alaska, bass fish were collected in 36 different lakes to measure the amount of mercury in the fish. Do the data provide enough evidence to show that the fish in Alaska lakes has more mercury than the allowable amount? Below, set up the Null Hypothesis Ho and the Alternative Hypothesis HA. Ho: H (? HẠ: H (?arrow_forwardA researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are H0:p = 0.4 and Ha: p < 0.4. The test statistic and p-value for the test are z = -3.01 and p-value = 0.0013. For asignificance level of a= 0.05, choose the correct conclusion regarding the null hypothesis.H0:________________________ Ha:_______________________Compare the p-value and a:_______________Decision:_________________________Conclusion:___________________________________________________________arrow_forwardThe data below were collected to test the effectiveness of a drug to lower systolic blood pressure. Blood pressure (in mm of mercury) was measured before and after treatment for 12 patients; the results are shown. The company claims the drug is effective.
