A researcher wants to estimate the true proportion of people who would buy items they know are slightly defective from thrift shops because of the lower price. After conducting a survey on a sample of 969 persons who regularly shop at thrift stores, he finds that 337 of the individuals would buy a slightly defective item if it cost less than a dollar.

Calculate the lower bound of a 90% confidence interval for the true proportion of people who would purchase a defective item. Take all calculations to three (3) decimal places.
