Respuesta :

To find the mean we will sum the prices (total price, including repeated values) and divide by the total number of computers, then

[tex]m=\frac{14\cdot1400+11\cdot800+3\cdot2600+6\cdot1500}{34}[/tex]

Using a calculator

[tex]\begin{gathered} m=\frac{45200}{34} \\ \end{gathered}[/tex]

Do the division (use a calculator)

[tex]\begin{gathered} m=\frac{45200}{34} \\ \\ m=1329.41 \end{gathered}[/tex]

The mean price is 1329.41
