hello i need help with these statistic questions thank you

question 20:

Determine the z-test statistic. z= - 1.78 (Round to two decimal places as needed.) Find the p-value. p-value = 0.076 (Round to three decimal places as needed.) Choose the correct conclusion. A. Reject Ho. The population proportion is significantly different from 0.24. B. Do not reject Ho. The population proportion is not significantly different from 0.24. O C. Do not reject Ho. The population proportion is significantly different from 0.24. O D. Reject Ho. The population proportion is not 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 24%. X B. Since the null hypothesis was rejected, the percentage of dangerous fish is definitely not 24%. C. Since the null hypothesis was not rejected, the percentage of dangerous fish could be 24%, but the actual population percentage is still unknown. O D. Since the null hypothesis was not rejected, the percentage of dangerous fish is definitely 24%.Some experts believe that 25% of all freshwater sh in a country have such high levels of mercury that they are dangerous to eat. Suppose a sh market has 250 sh tested, and 52 of them have dangerous levels of mercury. Test the hypothesis that this sample is not from a population with 25% dangerous sh, assuming that this is a random sample. Use a signicance level of 0.05. Comment on your conclusion. State the null and alternative hypotheses. [:1 A. H0: p=D.25 HA: p > 0.25 [:1 B. H0: p#0.25 HA: p=0.25 (:18. H0: p0.25 [:1 D. H0: p>D.25 HA: p
