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 tes the hypotheses Ho: p=0.10, Ha: p<0.10 To do so, she selects an SRS of 150 potatoes from the more than 3000 potatoes on the truck. Suppose that six of the potatoes sampled are found to have major defects. Which of the following assumptions for inference about a proportion, using a hypothesis test, are violated? O The data are an SRS from the population of interest. O There appear to be no violations. O The population is at least 10 times as large as the sample. On is so large that both npo and n(1-po) are 10 or more, where po is the proportion with major defects, if the null hypothesis is true.

O The data are an SRS from the population of interest. O There appear to be no violations. O The population is at least 10 times as large as the sample. n is so large that both npo and n(1-Po) are 10 or more, where po is the proportion with major defects, if the null hypothesis is true.
