To calculate:the expected average value of the 13 discrete temperatures.
Answer to Problem 20E
The average is less than trapezoidal rule approximation.
Explanation of Solution
Given information:
The average temperature to be 65.17 degrees when used the integral approximation, yet the average of the 13 discrete temperatures is only 64.69 degrees. Considering the shape of the temperature curve
Formula used:
The sum of all values and divided by total number of quantities.
Calculation:
The calculation of the average from basic average formula that is sum of all values and divided by total number of quantities then, average gives equal weight to all values. Here at end of interval, average gives equal weight to low values. So the value becauseof average is less than trapezoidal rule approximation.
Conclusion:
The average is less than trapezoidal rule approximation.
