Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is 2 inches. The heights of 6 randomly selected students are 71, 66, 72, 64, 69, and 72. - Sample mean (\(\bar{x}\)) = [redacted] - Margin of error at 99% confidence level = [redacted] - 99% confidence interval = [ [redacted], [redacted] ] [smaller value, larger value]
