A cell phone manufacturer would like to estimate the mean difference in battery lifespan for a phone in full-power
versus power-saver mode. They randomly select eight phones and determine the battery lifespan, in hours, for each
phone using each power mode. The data are displayed in the table.

What is the mean difference (low - full) and the standard deviation of the differences?
did=5.875. Si=0.899
dir = 5.875. dift = 0.961
*dit = 6,063, Sdir=0.899
ditt = 6,063, 5#=0.961
