Question

Fatima conducted an experiment where she asked people to estimate the temperature of glasses of water. She recorded how far the estimates were from the actual temperatures, using positive values for guesses that were too high and negative values for guesses that were too low. Her results are in the table below. Estimate -−minus actual temperature (\degree\text{C})(°C)left parenthesis, degree, C, right parenthesis Person A Person B Person C -3−3minus, 3 444 888 -1−1minus, 1 -4−4minus, 4 -2−2minus, 2 000 222 555 222 -3−3minus, 3 111 What is the mean value in Fatima's results? \degree\text{C}°Cdegree, C

Answer 1

0.75°C above actual Temperature

Step-by-step explanation:

Estimate −minus actual temperature

Person A     Person B          Person C

-3                   4                      8

-1                   -4                     -2

0                    2                      5

2                     -3                   1

Adding all these values

=  - 3 + 4 + 8  - 1 - 4 - 2  + 0 + 2 + 5  +  2  - 3  + 1

= 9  

Estimate is 9 deg above Actual Temperature in 12 readings

Mean Value = 9/12 = 0.75°C above actual Temperature
