A sample of 33 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
Number of computers: 7, 11, 15
Price in dollars: 2050, 1600, 2150
Find the mean price for this sample round your answer to the nearest dollar
To find the mean price for this sample, we sum up all the prices and divide by the total number of customers:
(7 * 2050) + (11 * 1600) + (15 * 2150) = 18650 + 17600 + 32250 = 68500
33 customers in total
Mean price = 68500 / 33 ≈ 2075
So, the mean price for this sample is approximately $2075.
To find the mean price for this sample, you need to calculate the sum of all the prices and then divide it by the total number of customers. Let's go step by step:
1. Multiply the number of computers by their corresponding prices:
- For 7 computers: 7 * $2050 = $14,350
- For 11 computers: 11 * $1600 = $17,600
- For 15 computers: 15 * $2150 = $32,250
2. Add up the total prices:
$14,350 + $17,600 + $32,250 = $64,200
3. Find the mean by dividing the total sum by the number of customers:
$64,200 / 33 = $1,947.27 (rounded to the nearest dollar)
Therefore, the mean price for this sample is approximately $1,947.
To find the mean price for this sample, you need to sum up all the prices and divide by the total number of customers. Let's calculate it step by step:
1. Multiply the number of computers by their respective prices for each customer:
For the first customer:
7 computers * $2050 = $14,350
For the second customer:
11 computers * $1600 = $17,600
For the third customer:
15 computers * $2150 = $32,250
2. Add up all the individual prices:
$14,350 + $17,600 + $32,250 = $64,200
3. Divide the total sum by the total number of customers:
$64,200 / 33 = $1,947.73 (rounded to two decimal places)
4. Round the mean price to the nearest dollar:
$1,948 (rounded to the nearest dollar)
Therefore, the mean price for this sample is $1,948.
