Some experts believe that 24% 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 tested, and 53 of them have dangerous levels of mercury. Test the hypothesis that this sample is not from a population with 24% dangerous fish, assuming that thi random sample. Use a significance level of 0.05. Comment on your conclusion.

Transcribed Image Text:Some experts believe that 24% 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
tested, and 53 of them have dangerous levels of mercury. Test the hypothesis that this sample is not from a population with 24% dangerous fish, assuming that thi
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. Do not reject Ho. The population proportion is significantly different from 0.24.
O B. Reject Ho The population proportion is not significantly different from 0.24.
O C. Do not reject Ho. The population proportion is not significantly different from 0.24.
O D. Reject Ho- The population proportion is significantly different from 0.24.
Comment on your conclusion. Are you saying that the percentage of dangerous fish is definitely 24%? Explain.
O A. Since the null hypothesis was rejected, the percentage of dangerous fish is definitely not 24%.
O B. Since the null hypothesis was not rejected, the percentage of dangerous fish could be 24%, but the actual population percentage is still unknown.
O C. Since the null hypothesis was rejected, the percentage of dangerous fish is definitely 24%.
O D. Since the null hypothesis was not rejected, the percentage of dangerous fish is definitely 24%.
