Power analysis of 65d and 75d data.

Results for the power analysis are shown for the 65d and 75d data. Higher power is seen in the ability to detect conditional differences between NS-UD and UD-UD in the 75d data relative to the 65d data which exhibits high variability within each condition. A comparison of the 65d vs. 75d data within a condition reveals higher power to detect age differences in the NS-UD condition.
