The manufacturer of the ColorSmart-5000 television set claims 95 percent of its sets last at least five years without needing a single repair. In order to test this claim, a consumer group randomly selects 400 consumers who have owned a ColorSmart-5000 television set for five years. Of these 400 consumers, 316 say their ColorSmart-5000 television sets did not need a repair, whereas 84 say their ColorSmart-5000 television sets did need at least one repair.

What is the lower confidence limit for the 90% confidence interval for the proportion of ColorSmart-5000 television sets that lasted five years without needing a repair? Include 3 decimal places in your answer.
