Chapter SH, Problem 24.6APP

To determine

To calculate: Mean of the given temperatures.

Answer to Problem 24.6APP

Mean of the given temperatures is $\underset{\_}{\text{633}\text{.5}°\text{C}}$ .

Explanation of Solution

Given:

Melting points of five different samples of a new aluminum alloy is as follows:

  $631.5°\text{C},632.3°\text{C},636.1°\text{C},637.4°\text{C},630.2°\text{C}$

Formula used:

Mean is given by,

  $\text{Mean = }\frac{\text{Sum of all terms}}{\text{Number of terms}}$

Calculation:

Mean of all the temperatures is calculated as:

  $\begin{array}{l}\text{Mean = }\frac{\text{Sum of all terms}}{\text{Number of terms}}\\ \text{Mean = }\frac{631.5°\text{C}+632.3°\text{C}+636.1°\text{C}+637.4°\text{C}+630.2°\text{C}}{5}\\ \text{Mean = 633}\text{.5}°\text{C}\end{array}$

Conclusion:

Mean of the given temperatures is $\underset{\_}{\text{633}\text{.5}°\text{C}}$ .
