Suppose Farmer Al says the average weight of an adult cow is 1350 pounds. Use this information to answer the following questions. Your friend, Yumi said there her cows were alwasy bigger than that. This elads you to believe that this claim is false. Write a null and alternative hypothesis that would correspond to this test.  Suppose you got a random sample of 9 cows that weighted an average of 1500 pounds and a sample standard deviation of 150lbs. What is the p-value of getting a sample 9 cows with an average weight of 1500lbs or more.  How would you interpret the probability of having a sample of 9 cows with an average weight of 1500 pounds or more at the alpha level of 0.05. Be sure to inerpret in context. Hint: the answer should include the words cows and weight.
