Question

a chemical engineer must report the average volume of a certain pollutant produced by the plants under her supervision. here are the data she has been given by each plant:
plant volume of pollutant
south fork 22.98 l
pinecrest 3.007 l
susquehanna 0.96 l
what average volume should the chemical engineer report? be sure your answer has the correct number of significant digits.

Explanation:

Step1: Find the sum of volumes

$22.98 + 3.007+0.96=26.947$ L

Step2: Calculate the average

There are 3 plants. The average volume $V=\frac{26.947}{3}\approx8.98233$ L

Step3: Determine significant - digits

The least number of decimal places among the original data is 2 (in 0.96 L). So, we round the average to 2 decimal places. The average volume is $8.98$ L

Answer:

$8.98$ L
