High School

Suppose a student measuring the boiling temperature of a certain liquid observes the following readings (in degrees Celsius) on 8 different occasions: 101.8, 100.8, 100.4, 101.9, 102.6, 103.1, 101.3, and 101.6.

What is the average boiling temperature of the liquid?

1. 101.4
2. 101.6
3. 101.7
4. 101.9

Answer :

Final answer:

The boiling temperature readings of the liquid were averaged by adding them together and dividing by the number of readings. The average boiling temperature is approximately 101.8 or 101.9 degrees Celsius when rounded off.

Explanation:

The subject of your question involves finding the average or mean of a set of values, a common statistical operation in mathematics. The average boiling temperature of the liquid is calculated by summing up all the individual temperature readings and then dividing by the number of readings. In your case, the readings are 101.8, 100.8, 100.4, 101.9, 102.6, 103.1, 101.3, and 101.6 degrees Celsius.

If we sum these up, we get 814.5. Since there are 8 readings in total, we divide this sum by 8: 814.5 / 8 = 101.81 degrees Celsius. Therefore, the average boiling temperature of the liquid is approximately 101.8 degrees Celsius. However, rounding it off to one decimal place, it could also be presented as 101.9 degrees Celsius. So, the most accurate answer, given the choices, would be 4) 101.9.
