You work for a candy company and the manufacturing manager claims that the production line produces bags of candy with an average of exactly 50 candies per bag. You are skeptical about this and you decide to test the claim by counting the candies in a sample of 9 bags. You discover in your sample that - Xx = 53 and s = 3. Determine whether or not you have enough statistical evidence to reject the manager's claim with a significance level of .05. In order to get full credit you need to include the following seven items in your answer. Circle each of these answers. 1. State the null and alternative hypotheses using mathematical symbols. 2. Give the symbol for the test statistic you will use to test your hypothesis. 3. Give the value of the test statistic. 4. Calculate the number of degrees of freedom if necessary. 5. Provide a range for the p-value (if you are using a table). You can also give the exact p- value if you are using a computer to calculate the answer. 6. Give a statistical result for your hypothesis test (Reject or Fail to Reject) and include a note explaining why that is the right conclusion. 7. Provide a sentence explaining your result in plain English with no statistical jargon.
