Question 6 of 10
MA_775_DIABLO [31]

The average of the following set of measurements is 20°C.

To find the average of the given set of measurements

Given:

Set of measurements = 27°C, 12°C, 31°C, 19°C, 23°C, 11°C, 17°C

Number of Observations = 7

Average = Sum of observations/Total number of observations

Sum of observations = 27°C+12°C+31°C+19°C+23°C+11°C+17°C

= 140

Total number of observations = 7

Substitute the values in the formula

= 140/7 = 20°C

Therefore, the average of the following set of measurements is 20°C
