Fatima conducted an experiment and found that 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
