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 50 potatoes from the over 2000 potatoes on the truck. then, the normal approximation to the binomial can safely be used for this significance test. the normal approximation to the binomial should not be used for this significance test. the alternative hypothesis should be ha: p > 0.10.
