• A loan officer compares the interest rates for 48-month fixed-rate auto loans and 48-month variable-rate auto loans. Two independent, random samples of auto loan rates are selected. The resulting data are: 
• 
  
• Fixed-rate: 8.9% 7.8% 7.6% 9.1% 6.8% 8.2% 7.6%
• 
  
• Variable-rate: 6.2% 4.5% 5.5% 4.4% 6.1% 6.9%
• 
  
• How many degrees of freedom are associated with the pooled variance estimate from these two samples?
