Here are summary statistics for randomly selected weights of newborn girls: n = 36, x = 3222.2 g, s =686.7 g. Use a confidence level of 95% to complete parts (a) through (d) below. a. Identify the critical value to / 2 used for finding the margin of error. ontents ta/2 = Plan (Round to two decimal places as needed.) and Resour b. Find the margin of error. E = 9 SE sible Resour (Round to one decimal place as needed.) c. Find the confidence interval estimate of H. se nase Options munication T (Round to one decimal place as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. O A. 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. O B. Approximately 95% of sample mean weights of newborn girls will fall between the lower bound and the upper bound. O C. One has 95% confidence that the sample mean weight of newborn girls is equal to the population mean weight of newborn girls. O D. 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
