The data in the accompanying table represent the length of life, in years, measured to the nearest tenth, of 30 similar fuel pumps. Complete parts (a) through (c) below. Click the icon to view the fuel pump data. (a) Construct a stem-and-leaf plot for the life in years of the fuel pumps, using the digit to the left of the decimal point as the stem for each observation Stem Leaf Frequency J▬▬▬UE IL (b) Set up a relative frequency distribution.
