A local brewery distributes beer in bottles labeled 32 ounces. A government agency thinks that the brewery is distributing less than that amount. The agency selects 44 of these bottles, measures their contents, and obtains a sample mean of 27.4 ounces with a population standard deviation of 1.23 ounce. Use a 0.07 significance level to test the agency's claim that the brewery is cheating its customers. (Round to four decimals) Ho: _________________________ Ha: _________________________ =______________ Which hypothesis represents the claim? Circle: Null Hypothesis or Alternative Hypothesis Find the critical values of the rejection region. (Show calculator function used, values plugged into calculator function, and final answer rounded to 4 decimals. Sketch the rejection region on the normal curve.) Test this hypothesis. (Show original formula, values then plugged into formula, and final answer rounded to 4 decimals) Decision (Reject or Fail to Reject): ___________________ Write a conclusion in context of this problem. At ___% level of significance, there ____________ enough evidence to _____________ the claim that _______________________________________________________________________________________ ______________________________________________________________________________________.
