A car company claims that only 15% of its cars require a major repair within 5 years of purchase. A random sample of 200 cars from the company showed that 20% of the sample required a major repair within 5 years of purchase. Assuming that the car company is correct that the population proportion is 15%, what is the probability of getting a sample proportion of 20% or more in a random sample of 200 cars? Round your answer to 3 decimal places.
