1. Effects of Greenhouse Soil vs. a Hydroponic System on Different Varieties of Tomato Plants Rachel Springer

2. Hypothesis Null: (Claim) The mean height of the plants in the hydroponics system will be greater than the mean height of the plants in soil. H₀: µ >38.664 Alternative: The mean height of the plant in the hydroponics system will be less than the mean height of the plants in the greenhouse soil. H₁: µ≤ 38.664

7. Conclusion I do not reject my null hypothesis and I do not reject my claim. There is not enough evidence to reject the null hypothesis. The average mean of the plants in the hydroponics systems was greater than the average height of the plant in the soil.
