if a confidence interval is given from 8.50 to 10.25 and the mean is known to be 9.375 what is the margin of error
Margin of error is given by=9.375-8.5=0.875, which is also equal to 10.25-9.375. Basically , for a both side equal confidence interval, maargin of error is given by Upper Confidence Limit- Mean or Mean-Lower Confidence Limit

Confidence Interval Given. Assume I created a 96% confidence interval for the mean hours studied for a test based on a random sample of 100 students. The lower bound of this interval was 3 and the upper bound was 16. Assume that when I created this interval I knew the population standard deviation. Using this information, (a) Calculate the width of the interval. ( b) Calculate the margin of error for the interval. (c) Calculate the center of the interval....
