An inspector checks large truck loads of potatoes to determine the proportion ? in the shipment with major defects, prior to the potatoes being used to make potato chips. If there is clear evidence that this proportion is less than 0.1, she will accept the shipment. To reach a decision, she will test the hypotheses ?0:?=0.1 versus ??:?<0.1 . To do so, the inspector selects a simple random sample of 150 potatoes from the more than 3000 potatoes on the truck. Only 8 of the potatoes sampled are found to have major defects. What is the value of the large‑sample ? test statistic? −1.91 1.91 −2.54
