In a study of a particular brand of laptop computer, one group of 9 batteries lasted an average of 17.8 hours before needing recharging, and a second group of 11 batteries lasted an average of 18.1 hours. the difference between the two groups was found to be statistically significant. are the results practically significant? why or why not?
yes, because the same brand of computer was used for all of the tests.
yes, because results that are statistically significant are also practically significant.
no, because the 0.3 hour difference in battery life was small.
no, because there were more batteries in the second group.
