Answer:
Not skewed
Step-by-step explanation:
Since, the given distribution that is {0,1,2,3,4,5,6,20,21,22,23,24,25} has a mean =[tex]\frac{0+1+2+3+4+5+6+20+21+22+23+24+25}{13}=\frac{156}{13}=12[/tex].
And the mode is the term which occurs frequently in the distribution, Since, in the given distribution, there is no term which is occurring frequently, therefore there is no mode for the given distribution, thus we cannot determine the skewness of the given distribution,
Hence the given distribution is not skewed.
