Answer 2

Answer: A. 51.9, 52, 49, 6

Explanation:

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

`{\text{Mean =}\frac{\text{Sum of observations}}{\text{Number of observations}}`

`{\text{Mean =}(363)/(7)=51.8571428571\approx51.9`

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

`=55-49=6`
