Answer: A. 51.9, 52, 49, 6

Step-by-step explanation:

The given data : 49, 49, 54, 55, 52, 49, 55

[tex]{\text{Mean =}\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]

[tex]{\text{Mean =}\dfrac{363}{7}=51.8571428571\approx51.9[/tex]

For Median , first we arrange observations in order.

49, 49, 49, 52, 54, 55, 55

Median = Middlemost observation = 52

Mode = Most repeated observation = 49

Range = Maximum number -Minimum number

[tex]=55-49=6[/tex]
