Explanation / Answer

Q.28 : Here the box plot contains two outliers. Also from the mean, lower quartile and upper quartile positions in box plot we can say that data is not normally distributed. Because if data is normally distributed then mean will be at the middle of lower and upper quartile. Hence the correct option is B) No there are outliers and data is not normally distributed.

Q.29: Similarly in this case there are no outliers but the data is not normally distributed because the mean is not exactly at the middle of first and third quartile. Hence the correct option is B) No, There are no outliers but data is not normally distributed.
