A certain city's Department of Transportation DOT repairs about 80,000 potholes per year. The DOT completes 90% of the repairs on the reported potholes within two weeks of the report. Suppose the DOT annually takes a random sample of 75 of the reported potholes and calculates the proportion ^p of potholes repaired within two weeks. Which of the following distributions is the best approximation of the sampling distribution of ^p?
