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 24 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 a random sample. Use a significance level of 0.05. Comment on your conclusion. find the z-score and the p-value
