Home mortgage rates for 30-year fixed rate loans vary throughout the country (following the normal distribution). During the summer of 2000, data available from various parts of the country suggested that the standard deviation of the interest rates was .096. The corresponding measure of variance was (.096)*(.096)=.009216. Consider a follow-up study completed in the summer of 2001. The interest rates for 30-year fixed rate loans at a sample of 20 lending institutions had a sample standard deviation of .114. Conduct a hypothesis test of to see whether the 2001 sample data indicate that the variability in interest rates has changed. Use . What is your conclusion?
