Answer: The skew in the distribution is <u>positive</u>. If the writer writes for two more days and creates 5 and 7 comic strips, respectively, the difference of the mean and the median for the new data set is <u>0.28</u>.
Step-by-step explanation:
Given data : {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 8}
Now, data is already arranged in ascending order.
Since number of observations (16) is even.
Median = Mean of
=Mean of
⇒Median
Since, Median < Mean
Then , the data is positively skewed.
The new data set : {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 8,5,7}
Number of data values :18
Now,
Again number of observations (18) is even.
Median = Mean of
=Mean of
⇒Median
Difference of the mean and the median for the new data set is
