A principal of a large high school wants to estimate the average GPA of the students at the school with 96% confidence. She randomly selects one grade level and then calculates the average GPA of all the students in that grade level to be 2.5 with a standard deviation of 0.7. Determine if the conditions have been met: Random condition: 10% condition: Normal/Large Sample condition: Are all the conditions for inference met?

A principal of a large high school wants to estimate the average GPA of the students at the school with 96% confidence. She randomly selects one grade level and then calculates the average GPA of all the students in that grade level to be 2.5 with a standard deviation of 0.7.
**Determine if the conditions have been met:**
- **Random condition:** [Dropdown selection]
- **10% condition:** [Dropdown selection]
- **Normal/Large Sample condition:** [Dropdown selection]
**Are all the conditions for inference met?** [Dropdown selection]
**Explanation:**
This section involves assessing whether certain statistical conditions are met to estimate the average GPA with a specified confidence level. These conditions ensure that the statistical inference is valid, including randomness, a sample size that does not exceed 10% of the population, and whether the sample size is sufficiently large or the population distribution is normal. The dropdown options enable selection based on whether each condition has been satisfied.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7c6d136e-2074-4849-9b3d-0df6994baeb8%2F6f5ee9ea-6550-46a9-893e-a3d295303ffd%2F3m4iv1_processed.png&w=3840&q=75)
