Eclipses of Saturnian satellites. Saturn has ?ve satellites that rotate around the planet. Astronomy (August 1995) lists 19 different events involving eclipses or occults of Saturnian satellites during the month of August. For each event, the percent of light lost by the eclipsed or occulted satellite at midevent is recorded in the table.

(a) Construct a stem-and-leaf display for light loss percentage of the 19 events.
(b) Locate on the stem-and-leaf plot, part a, the light losses associated with eclipses of Satur- nian satellites. (Circle the light losses on the plot.)
(c) Based on the marked stem-and-leaf display, part b, make an inference about which event type (eclipse or occult) is more likely to lead to a greater light loss.
