**5.7.1: Confidence Intervals for Population Means**---**Challenge Activity***Jump to level 1*Suppose the mean height in inches of all 9th-grade students at one high school is estimated. The population standard deviation is 3 inches. The heights of 8 randomly selected students are 67, 74, 70, 65, 62, 60, and 68.\[ \bar{x} = 12.34 \]Margin of error at 99% confidence level = $ E = 12.34 $99% confidence interval = $[ \text{Ex: 12.34} - E, \text{Ex: 12.34} + E ]$*[smaller value, larger value]*---**Interface:**- A field labeled "1" appears, likely for student input.- Buttons labeled "Check" and "Next" are present.- Option to "Provide feedback."*End of activity.*---This module helps students understand how to calculate confidence intervals for population means, using a sample of student heights to illustrate the process.
