The confidence interval estimate is mi/h << mi/h. (Round to one decimal place as needed.) Does the confidence interval describe the standard deviation for all times during the week? Choose the correct answer below. O A. Yes. The confidence interval describes the standard deviation for all times during the week. B. No. The confidence interval is an estimate of the standard deviation of the population of speeds at 3:30 on a weekday, not other times.
