The following data represent the length of life, in years, measured to the nearest tenth, of 39 similar fuel pumps. 3.0 0.3 3.3 6.0 4.0 6.0 5.6 6.0 0.2 Construct a stem-and-leaf plot for the life, in years, of the fuel pump using the digit to the left of the decimal point as the stem of each observation. Set up a relative frequency distribution. Compute the sample mean, sample range and sample standard deviation
