QUESTION

# Stat 250 DAA

Experts believe that 20% of all freshwater fish in the United States have such a high level of mercury that they are dangerous to eat. Suppose a fish market has 250 fish tested and 60 of them have dangerous levels of mercury. Test the hypothesis that this sample is not from a population with 20% dangerous fish. Use a = 0.10.

State the null and alternative hypotheses. State the significance level for this problem. List the conditions that allow you to use the test statistic, and, if appropriate, calculate the test statistic. Calculate the p-value and include the probability notation statement. State whether you reject or do not reject the null hypothesis. State your conclusion in context of the problem (i.e. interpret your results). Use StatCrunch to verify your test statistic and p-value.GET YOUR EXPERT ANSWER ON STUDYDADDY
