A coach uses a new technique in training middle distance runners. The times for 9 randomly selected, independent athletes to run 800 meters before and after this training are shown below. Assume the distribution of differences are normally distributed
Before 115.2 120.9 108.0 112.4 107.5 119.1 121.3 110.8 122.3
After 116.0 119.1 105.1 111.9 109.1 115.1 118.5 110.7 120.9
Build and Interpret 90% confidence interval for the true mean difference in 800-meter times.
