Identify the critical value t12 used for finding the margin of error. Round to two decimal places as needed.) . Find the margin of error. Round to one decimal place as needed.) E. Find the confidence interval estimate of u. Round to one decimal place as needed.) 1. Write a brief statement that interprets the confidence interval. Choose the correct answer below. OA. One has 95% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of newborn girls. OB. There is a 95% chance that the true value of the population mean weight of newborn girls will fall between the lower bound and the upper bound. OC. One has 95% confidence that the sample mean weight of newborn girls is equal to the population mean weight of newborn girls. O D. Approximately 95% of sample mean weights of newborn girls will fall between the lower bound and the upper bound.
