Data: 25, 25, 26, 26, 27, 27, 28, 28, 29, 29

Answer:

18

Explanation:

A left skewed data is one which it's tail is to the left of the distribution. This means the data is negatively skewed. One of the difference various characteristics of a left skewed data wh in could help find an answer to the question is that, for a left skewed distribution, the mean of the data is lower lesser than other measures of center and the mean falls to the left side of de of the peak. Hence, to create a data that is left skewed, we add the value from the options which will decrease the initial value of Mean.
