a. What is the average cost for the tablets (to 2 decimals)?
$

b. Compare the average cost of tablets with a Windows operating system to the average cost of tablets with an Android operating system (to 2 decimals).

Average cost with a Windows operating system = $

Average cost with Android operating system = $

c. What percentage of tablets use a CPU manufactured by TI OMAP (to the nearest percent)?
%

d. What percentage of tablets use an Android operating system (to the nearest percent)?
%

Answer 1

Part (a) - Average cost of the tablets:

Average cost of the tablets = Total cost of the tablets / Number of tablets

Total cost of the tablets= $599 + $299 + $499 + $668 + $590 + $360 = $3015

Number of tablets = 6

Average cost of the tablets = $3015 / 6 = $502.50

Part (b) - Comparison:

Step 1:

Average cost of the windows operating system :

Total cost of the windows operating system tablets / Number of windows operating system tablets

Total cost of the windows operating system tablets = $599 + $668 + $590 = $1857

Number of windows operating system tablets = 3

Average cost of the windows operating system tablets = $1857 / 3 = $619.00

Step 2:

Average cost of the android operating system :

Total cost of the android operating system tablets / Number of android operating system tablets

Total cost of the android operating system tablets = $299 + $360 = $659

Number of android operating system tablets = 2

Average cost of the android operating system tablets = $659 / 2 = $329.50

Step 3: Comparison

The average cost of tablets with a window operating system is 1.9 times ($619 / $329.50) higher than the average cost of tablets with a android operating system.

Part (c) - Percentage of tablets use a CPU manufactured by TI OMAP:

Percentage of tablets use a CPU manufactured by TI OMAP:

=Number of TI OMAP CPU Manufacturer / Total number of CPU manufactures

Number of TI OMAP CPU Manufacturer = 1

Total number of CPU manufactures = 6

Percentage of tablets use a CPU manufactured by TI OMAP = 1 / 6 * 100 = 17%

Part (d) - Percentage of tablets use a Android operating system:

Percentage of tablets use a Android operating system:

=Number of Android operating system / Total number of operating system

Number of Android operating system = 2

Total number of operating system = 6

Percentage of tablets use a Android operating system = 2 / 6 * 100 = 33%

All the best...
