Question

The following data represent the battery life, in hours, for a random sample of 10 charges on a fifth generation iPod music player.

7.3 10.2 12.9 10.8 12.1

6.6 10.2 9.0 8.5 7.1

10) How large a sample would be necessary to estimate the mean number of hours the battery will last on the player with a margin of error of .5 with 97% confidence? Since the population standard deviation σ is not known use the sample standard deviation s from problem 2.
