Question

A sample of 34 customers was taken at a local computer store. The customers were asked the prices of the computers they had bought. The data are summarized in the following table. Find the mean price for the sample. Round your answer to the nearest dollar

Answer 1

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

$m=\frac{14\cdot1400+11\cdot800+3\cdot2600+6\cdot1500}{34}$

Using a calculator

$\begin{gathered} m=\frac{45200}{34} \\ \end{gathered}$

Do the division (use a calculator)

$\begin{gathered} m=\frac{45200}{34} \\ \\ m=1329.41 \end{gathered}$

The mean price is 1329.41
