p-value =O (Round to three decimal places as needed.) Choose the correct conclusion. O A. Reject Ho. The population proportion is not significantly different from 0.25. O B. Do not reject Ho. The population proportion is significantly different from 0.25. OC. Reject Ho. The population proportion is significantly different from 0.25. O D. Do not reject Ho. The population proportion is not significantly different from 0.25. Comment on your conclusion. Are you saying that the percentage of dangerous fish is definitely 25%? Explain. O A. Since the null hypothesis was rejected, the percentage of dangerous fish is definitely 25%. O B. Since the null hypothesis was not rejected, the percentage of dangerous fish could be 25%, but the actual population percentage is still unknown. c. Since the null hypothesis was rejected, the percentage of dangerous fish is definitely not 25%. D. Since the null hypothesis was not rejected, the percentage of dangerous fish is definitely 25%.

Transcribed Image Text:Some experts believe that 25% 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 61 of them have
dangerous levels of mercury. Test the hypothesis that this sample is not from a population with 25% dangerous fish, assuming that this is a random sample. Use a significance level of 0.05. Comment on
your conclusion.
State the null and alternative hypotheses.
O A. Ho: p<0.25
Ha: p>0.25
О В. Но: р3D0.25
Ha:p>0.25
О С. Но: р30.25
Ha: p#0.25
O D. Ho: p> 0.25
Ha:p<0.25
O E. Ho: p#0.25
Ha:p=0.25
