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 0.10, he will reject the shipment. He will test the hypotheses H0: p = 0.10, Ha: p < 0.10. He selects an SRS of 100 potatoes from the over 2000 potatoes on the truck. Suppose that 6 of the potatoes sampled are found to have major defects. Reference: Ref 19-6
A 95% confidence interval for the true proportion of potatoes in the truck that have major defects is
A. 0.034 to 0.086.
B. 0.009 to 0.111.
C. 0.051 to 0.103.
D. 0.026 to 0.128.
