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 65, 75, 64, 65, 62 and 67. * = Ex: 12.34 Margin of error at 99% confidence level = Ex: 1.23 99% confidence interval = [Ex: 12.34 Ex: 12.34] [smaller value, larger value]

Question
The image contains a problem about estimating the mean height of 9th-grade students in a high school. The problem states:

- The population standard deviation is 2 inches.
- Heights of 6 randomly selected students: 65, 75, 64, 65, 62, and 67 inches.

It asks for:

1. The sample mean (represented as \(\bar{x}\)), with an example placeholder: "Ex: 12.34".
   
2. The margin of error at a 99% confidence level, with an example placeholder: "Ex: 1.23".

3. The 99% confidence interval, with example placeholders: "[Ex: 12.34, Ex: 12.34]".

Below the questions, there are two navigation buttons, "Check" and "Next".

This setup is meant to guide students in calculating confidence intervals for a given sample using the known population standard deviation.
