indicate that the mean shelf life of a 4.5-litre (Lljug of chlorine is 2160 hours (90 days). As an experiment, Holdlonger was added to the 6 The liquid chlorine added to swimming pools to combat algae has a relatively short shelf life before it loses its effectiveness. Records chlorine to find whether it would increase the shelf life. A sample of ninejugs of chlorine had these shelf lives (in hours): 2172 | 2167 | 2188 | 2162 | 2176 | 2183 | 2177 | 2152 | 2195 | At the 0.025 level, has Holdlonger increased the shelf life of the chlorine? a.
