Problem 2E

Construct a 95% confidence interval for the population variance σ2 if a sample of size 25 has standard deviation s = 15.

Step-by-Step Solution:
Step 1 of 3

Previously discussed concepts: 1. Crude Birth Rate (CBR) ​​- total number of live births per 1,000 people per year Crude Death Rate (CDR) ​​- total number of deaths per 1,000 people per year 2. Rate of Natural Increase ​​- difference between CBR and CDR In the order of → CBR - CDR 3. Net Reproduction Ratio (NRR)​​ - Relates number of women in a society to number of female children they have Ex: NRR of 2.0 might indicate next generation may have twice as many potential mothers - Higher NRR ​might ​indicate rapid growth population Factors to consider: high NRR doesn’t necessarily mean population will increase rapidly This may be due to: - High infant mortality rates - Low society status (female infanticide: male children are more valued than women) - Limited
