The following data represent the length of life, in seconds, of 50 fruit flies subject to a new spray in a controlled laboratory experiment:

17	20	10		23	13	12	19	18	24
12	14			13			10	13
16	18		13		32			10	11
13		18		10		27	19	16
	10		14	15	10				15

(a) Construct a double-stem-and-leaf plot for the life span of the fruit flies using the stems 0∗, 0·, 1∗, 1·, 2∗, 2·, and 3∗such that stems coded by the symbols _ and · are associated, respectively, with leaves 0 through 4 and 5 through 9.

(b) Set up a relative frequency distribution.

(c) Construct a relative frequency histogram.

(d) Find the median.
