You set up an experiment to test your hypothesis.You place 100 one-year-old red oaks in one-gallon pots, with equal amounts of soil in each. Once a month for a year, you will count the totalnumber of leaves and then determine the percentage of damaged leaves found on each tree.4)Which experimental design would be most appropriate to test the hypothesis that acidprecipitation damages the leaves of young red oak trees?a)You water each tree daily with 100 ml of water, giving all 100 trees highlyacidic water.b)You water each tree daily with 100 ml of water, giving 50 trees highly acidicwater, and 50 trees water with neutral (not acidic) water.c)You water each tree daily with 100 ml of water, giving 50 trees highly acidicwater, and 50 trees slightly acidic water.d)You water 50 trees daily with 100 ml of highly acidic water, and youwater 50 trees once a week with 100 ml of water with neutral (not acidic) water.
You proceed with your experiment and collect data.These graphs summarize your data.5)What can you conclude from these results?
