Heip A study on the personality characteristics of drug dealers sampled 100 convicted drug dealers and scored them each on the Wanting Recognition (WR) Scale, which provides a quantitative measure of a person's need for approval and sensitivity to social situations. (Higher scores indicate a greater need for approval.) The sample of drug dealers had a mean WR score of 56, with a standard deviation of 5. Use this information to find an interval estimate of the mean WR score for all convicted drug dealers. Use a confidence level of 99%. Interpret the result. Construct a 99% confidence interval and interpret the result. (Round to two decimal places as needed.) O A. The 99% confidence interval for mean WR score indicates that the true mean WR score for convicted drug dealers is between and with 99% confidence. O B. The 99% confidence interval for mean WR score indicates that 99% of all drug dealers have a WR score between and O C. The 99% confidence interval for mean WR score indicates that 99% of convicted drug dealers have a WR score between and and with 99% confidence. O D. The 99% confidence interval for mean WR score indicates that the true mean WR score for all drug dealers is between
