The image is not very much enlarged, and is slanted, so answers might be just approximate. (a) median is 39 or 40, your choice. (b) 3rd quartile of y looks 47 or 48 (c) variable y has more disperson, since both the extremes and the quartiles are spread out longer that those of variable x. (d) since both halfs of the blue box (of x) and both lines outside of the box are basically equal, variable x's distribution is very much symmetric. Sorry, cannot read question part (e) completely.
