Here are summary statistics for randomly selected weights of newborn girls: n = 36, x =3216.7 g, s = 688.5 g. Use a confidence level of 90% to complete parts (a) through (d) below. CELED a. Identify the critical value to / 2 used for finding the margin of error. ta/2= (Round to two decimal places as needed.) b. Find the margin of error. E = 9 (Round to one decimal place as needed.) c. Find the confidence interval estimate of p. (Round to one decimal place as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. O A. There is a 90% chance that the true value of the population mean weight of newborn girls will fall between the lower bound and the upper bound. O B. Approximately 90% of sample mean weights of newborn girls will fall between the lower bound and the upper bound. O C. One has 90% confidence that the sample mean weight of newborn girls is equal to the population mean weight of newborn girls. O D. One has 90% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of newborn girls
