If n=26, (x-bar]=44, and 5:2, find the margin of error at a 90% confidence LeveL Give your answer to two decimal places. Assume that a sample is used to estimate a population mean p. Find the margin of error ME. that corresponds to a sample of size 12 with a mean of 26.8 and a standard deviation of 10.? at a confidence level of 99.5%. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. M.E. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places
