Let's break down the problem step by step. ### Part (a): Units of Measurement We need to identify which units could be used to measure the height of students. The options provided are: - hours - centimeters - seconds - inches - feet **Analysis:** - **Hours**: This unit measures time, not height. **Not applicable.** - **Centimeters**: This is a metric unit commonly used to measure height. **Applicable.** - **Seconds**: This unit measures time, not height. **Not applicable.** - **Inches**: This is an imperial unit commonly used to measure height. **Applicable.** - **Feet**: This is also an imperial unit used to measure height. **Applicable.** **Conclusion for Part (a)**: The applicable units for measuring height are **centimeters, inches, and feet**. ### Part (b): Best Procedure to Find Average Height We need to evaluate the options for finding the average height of students in the 12th grade: 1. **Ask for 50 volunteers from the 12th grade to state their own heights.** - This method may introduce bias, as those who volunteer may not represent the entire population. **Not the best option.** 2. **Measure the heights of 5 volunteers from the 12th grade.** - Similar to the first option, this is a small sample size and may not be representative. **Not the best option.** 3. **Randomly pick 50 students from the 12th grade and measure their heights.** - This method uses random sampling, which is a good way to ensure that the sample is representative of the entire population. **Best option.** 4. **Randomly pick 5 students from the 12th grade and have them state their own heights.** - While this option uses random selection, the small sample size and self-reporting can lead to inaccuracies. **Not the best option.** **Conclusion for Part (b)**: The best procedure to find the average height is to **randomly pick 50 students from the 12th grade and measure their heights**. ### Summary of Answers - **Part (a)**: Centimeters, inches, feet - **Part (b)**: Randomly pick 50 students from the 12th grade and measure their heights.
