Question

An inspector inspects large truckloads of potatoes to determine the proportion p in the shipment with major defects prior to using the potatoes to make potato chips. Unless there is clear evidence that this proportion is less than 0.10, she will reject the shipment. To reach a decision, she will test the hypotheses H0: p = 0.10, Ha: p < 0.10 using the large sample test for a population proportion. To do so, she selects an SRS of 100 potatoes from the over 2000 potatoes on the truck. Suppose that 16 of the potatoes sampled are found to have major defects. The P-value of her test is Answer a. 0.16 b. 0.977 c. 0.0400
