A manufacturer wants to determine whether the distance between two holes stamped into a metal part is meeting speci cations. A sample of 50 parts was taken, and the distance was measured to nearest tenth of a millimeter. The results were:

(a) Form a stem-and-leaf diagram of the measurements.

(b) Find the median, lower quartile, and upper quartile of the measurements.

(c) Sketch a boxplot of the measurements.

(d) Put the measurements in a frequency table with the following classes:

(e) Construct a histogram of the measurements.

(f) Construct a cumulative frequency polygon of the measurements. Show the median and quartiles.
