Question

a sample of 31 customers was taken at a computer store. each customer was asked the price of the computer bought. find the mean price- round to the nearest dollar

Answer 1

Given the table that shows the number of computers and their corresponding price paid for each, you can find the Mean Price as follows (remember that the Mean is the average of the values given in the data set):

1. Find the Sum of:

`(7\cdot1400)+(19\cdot1050)+(5\cdot2700)`

Then, you get:

`=9800+19950+13500=43250`

2. Divide the Sum by the number of values in the data set (in this case, is the total number of computers. Then, you get:

`Mean=(43250)/(31)\approx1395`

Hence, the answer is:

`Mean\text{ }Price\approx\text{ \$}1395`
