Recent research has demonstrated that music-based physical training for elderly people can improvebalance,walkingefficiency,and reduce the risk of falls (Trombetti et al., 2011).As part of the training, participants walked in time to music and responded to changes in the music's rhythm during a 1-hour per week exercise program. After 6 months, participants in the training group increased their walking speed and their stride length compared to individuals in the control group. The following data are results obtained in the study:

Exercise Group= 24,25,22,24,26,17,21,22,22,19,24,23,23,28,25,23

Control Group. stride length= 26,23,20,21,20,16,21,17,18,23,16,20,25,19,17,17

Do the results indicate a significant difference in the stride length for the two groups? Use a two-tailed test with alpha = .05.
