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 15% of bags are overfilled, then they stop production to fix the machine.
They define overfilled to be more than 1 ounce above the weight on the package. The engineer weighs 100 bags and finds that 21 of them are overfilled.
He plans to test the hypotheses: H0: p = 0.15 versus Ha: p > 0.15 (where p is the true proportion of overfilled bags).
What is the test statistic?
