Aschool sells boxes of cookies each year for a charity fund. the data set shows the number of boxes the 10 families living on willow avenue buy, on average, every year.
{2, 3, 2, 2, 0, 5, 2, 1, 1, 3}
does this data have negative, positive, or zero skew?

This data set has zero skew as it is symmetric.

We know that the symmetry exist in a data when the mean, median and mode of the data is same.

i.e. we are given a set of data as:

              {2, 3, 2, 2, 0, 5, 2, 1, 1, 3}

    0  1   1   2   2   2   2   3   3   5

Hence, the value that occur in the middle is: 2

Hence, we have Median=2

              Hence, Mean=2.1

Here 2 occurs most number of times i.e. 4 times and hence we have:

                   Mode=2

Now, as the Mean, Median and Mode of the data are approximately same.

      Hence, we get the data is symmetric and hence has a zero skew.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
