A researcher is interested in estimating the mean blood alcohol content (BAC) of people arrested for driving under the influence. The sample consists of 250 individuals with a  mean BAC of 0.145. Based on past data, the researcher assumes a population standard deviation of 0.065. What is the margin of error for a 90% confidence interval in this scenario?  (A) 0.004 (B) 0.006 (C) 0.107 (D) 0.008 If you feel the answer is none of the choices given, submit no answer to the question.
