Some experts believe that 16% of all freshwater fish in a country have such high levels of mercury that they are dangerous to eat. Suppose a fish market has 200 fish tested, and 26 of them have dangerous levels of mercury. Test the hypothesis that this sample is not from a population with 16% dangerous fish, assuming that this is random sample. Use a significance level of 0.05. Comment on your conclusion. z= (Round to two decimal places as needed.) Find the p-value. p-value = (Round to three decimal places as needed.) Choose the correct conclusion. O A. Reject Ho- The population proportion is significantly different from 0.16. O B. Reject Ho- The population proportion is not significantly different from 0.16. OC. Do not reject Ho. The population proportion is significantly different from 0.16. O D. Do not reject Ho. The population proportion is not significantly different from 0.16. Comment on your conclusion. Are you saying that the percentage of dangerous fish is definitely 16%? Explain. O A. Since the null hypothesis was rejected, the percentage of dangerous fish is definitely 16%. O B. Since the null hypothesis was rejected, the percentage of dangerous fish is definitely not 16%. OC. Since the null hypothesis was not rejected, the percentage of dangerous fish could be 16%, but the actual population percentage is still unknown. O D. Since the null hypothesis was not rejected, the percentage of dangerous fish is definitely 16%.
