Question 18 5 points Save Answer As part of an experiment on root metabolism, a plant physiologist grew birch tree seedlings in the greenhouse. He flooded four seedlings with water for one day and kept four others as controls. He then harvested the seedlings and analyzed the roots for ATR content. The results (nmol ATP per mg tissue) are shown in the table. [Note: Formula (6.7.1) yields 6 df.] ? Flooded Control n 4 4 1.190 1.785 V S 0.184 0.241 Using hypotheses testing with a non-directional alternative, study the effect of flooding over the difference H1 - H2 , where u] is the population mean for flooded and u2 is the population mean for the control. Find the value of the t-statistic and the p-value. O-2.68 and 0.0005
