The liquid chlorine added to swimming pools to combat algae has a relatively short shelf life before it loses its effectiveness. Record indicate that the mean shelf life of a 4.5-litre (L) jug of chlorine is 2160 hours (90 days). As an experiment, Holdlonger was added to chlorine to find whether it would increase the shelf life. A sample of nine jugs of chlorine had these shelf lives (in hours): 2169 2175 2174 2170 2185 2186 2195 2167 2160 At the 0.025 level, has Holdlonger increased the shelf life of the chlorine? a. What is the decision rule? (Round the final answer to 3 decimal places.) Reject Ho: H s 2160 and accept H: µ> 2160 when the test statistic is (Click to select) + b. Compute the value of the test statistic. (Round the final answer to 2 decimal places.) Value of the test statistic c. What is your decision regarding Ho? (Click to select) :) Ho. d. Determine or estimate the p-value.
