The liquid chlorine added to swimming pools to combat algae has a
relatively short shelf life before
it loses its effectiveness. Records indicate that the mean shelf life
of a 5-gallon jug or chlorine is 2,160
hours (90 days). As an experiment, Hondlonger was added to the
chlorine to find whether it would
increase the shelf life. A sample of nine jugs of chlorine had these
shelf lives (in hours):
2, 1592, 1702, 1802, 1792, 1602, 1672, 1712, 1812, 185			
At the .025 level, has Holdlonger increased the shelf life of the
chlorine? Estimate the p-value.
