Answer 1

The mean is also known as the average. For this problem, we want to find out the average distance that the guesses were from the true temperature. To do this, we need to add up all of the values and divide them by the number of values we have.

Person A:

-3 + -1 + 0 + 2 = -2

4 values

Person B:

4 + -4 + 2 + -3 = -1

4 values

Person C:

8 + -2 + 5 + 1 = 12

4 values

Totals:

-2 + -1 + 12 = 9

4 + 4 + 4 = 12 values

Find average:

9/12 = 0.75

The mean value in Fatima's results is 0.75.

Hope this helps!! :)

Answer 2

Answer:

0.75

Step-by-step explanation:

Person A's average: (-3-1+0+2)/4

= -0.5

Person B's average: (4-4+2-3)/4

= -0.25

Person C's average: (8-2+5+1)/4

= 3

Overall average:

(-0.5 - 0.25 + 3)/3 = 0.75
