This is not a graded question. This is a subsequent question, as the last answer I received was incorrect. This is a NEW question. Please answer all parts ### 6.2.1: 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 4 inches. The heights of 8 randomly selected students are **70, 68, 67, 66, 67, 71, 62, and 62**.\[\bar{x} = \text{Ex: 12.34}\]**Margin of error at 95% confidence level** \[\text{Ex: 1.23}\]**95% confidence interval**\[= \left[ \text{Ex: 12.34} , \text{Ex: 12.34} \right]\][smaller value, larger value][Input Box: 1] [Input Box: 2][Button: Check][Button: Next]##### FeedbackIn this educational exercise, users are prompted to calculate the margin of error and the 95% confidence interval for the mean height of students given the provided population standard deviation and sample data. Users are expected to input their answers and check their results.Note: The values "Ex: 12.34" and "Ex: 1.23" indicate example values or placeholders that students should replace with their calculated answers. The system allows students to input the smaller and larger values of the confidence interval.
