Suppose a random sample of 1500 registered voters was surveyed about energy issues. If 230 of the 1500 responded that they would favor drilling for oil in national parks, estimate the proportion p of registered voters who would favor drilling for oil in national parks. Construct a 95% con dence interval, provide its interpretation in the context of the problem and verify the respective assumptions that validate the use of a normal approximation.
