Answer 2

Answer:

hey here is your answer

pls mark it as brainliest

Step-by-step explanation:

so here median=26

mode=29

so using

mean-mode=3(mean-median)

ie mean-29=3(mean-26)

ie mean-29=3.mean-78

so 2.mean=49

ie mean=24.5

hence mean of score is 24.5

so as mode>median>mean

we can say that the data is negatively skewed ie is asymmetric in nature
