It is believed that 9% of children in Los Angeles face housing insecurity. How does Avocado Park compare based on your estimate in part e? g. If Jupiter wishes to lower her margin of error to 2% while maintaining a 90% level of confidence, how large a sample would she need? h. If Jupiter wishes to lower her margin of error to 2% while maintaining a 90% level of confidence but she doesn't trust the results of her previous survey, how large a sample could she possibly need?
