A group of researchers want to determine if life satisfaction declines following divorce. To test this hypothesis, they collected data on life satisfaction from 45 individuals at two time points: 6 months before divorce and 1 month after divorce. They observed that the average life satisfaction at time 1 was 6.5 and the average life satisfaction at time 2 was 5.9. The sum of squares for the difference scores (SSD) was 210. Use the critical-value approach for a dependent samples...
