A quality control engineer at a potato chip company tests the bag filling machine by weighing bags of potato chips. Not every bag contains exactly the same weight. But if more than 18% of bags are over-filled then they stop production to fix the machine. They define over-filled to be more than 1 ounce above the weight on the package. The engineer weighs 178 bags and finds that 47 of them are over-filled. He plans to test the hypotheses Ho: p= 0.18 versus H: p > 0.18. What is the test statistic? (Please round your answer to two decimal places if necessary.) A quality control engineer at a potato chip company tests the bag filling machine by weighing bags of potato chips.
