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, p, is less than 0.1, he will reject the shipment. He selects an SRS of 200 potatoes from the more than 5000 potatoes on the truck. Twelve of the potatoes sampled are found to have major defects. Using the plus four method, a 95% confidence interval for the true proportion of potatoes in the truck that have major defects is:

A. 0.027 to 0.093.
B. 0.009 to 0.111
C. 0.034 to 0.103.
D. 0.051 to 0.103.
