A laboratory tested a simple random sample of twelve chicken eggs and found that the data fit a nomal distribution and that mean amount of cholesterol was 225 milligrams with ans = 15.7 milligrams. Find the margin of error and confidence interval that corresponds to the given statistics and a confidence level of 95%. A E= 10.0354, CI = (212.0226, 237.9236) C) E= 6.2246, CI = (218.3254, 238.6984) B) E = 2.2546, CI = (216.0652, 233.9652) D) E= 9.9753, CI = (215.0247,234.9753)​
