Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is 5 inches. The heights of 9 randomly selected students are 66, 70, 68, 73, 65, 66, 68, 67 and 68. = Ex: 12.340 Margin of error at 90% confidence level = Ex: 1.23 90% confidence interval = [Ex: 12.34 Ex: 12.34] [smaller value, larger value]
