Tablet Computers. Tablet personal computers such as iPad and Kindle Fire are one-piece portable computers that typically offer a touchscreen. Tablets are available in different sizes but generally offer a screen that is greater than 7 inches diagonally. Consumer Reports reviews tablets of different sizes and Internet capabilities. The battery lives, in hours, for a sample of tablets with screen sizes between 9 and 12 inches are provided in the following table.

Explanation / Answer
The The battery lives, in hours, for a sample of tablets is given as,
8.4, 5.6, 10.9, 10.8, 11.5, 8.0, 8.5, 12.9
Mean of the data is
(8.4 + 5.6 + 10.9 + 10.8 + 11.5 + 8.0 + 8.5 + 12.9) / 8 = 9.575
So, B is correct answer.
The data in sorted order is
5.6, 8.0, 8.4, 8.5, 10.8, 10.9, 11.5, 12.9
Median of the data is the average of the middle two elements
= (8.5 + 10.8) / 2 = 9.65
So, F is the correct answer.
As, all data values are different, there is no mode in this data set.
So, D is the correct answer.
Range of the data = Max value - Min value = 12.9 - 5.6 = 7.3
So, A is the correct anser
