Question

The height of the plant will increase as the ph increases from pH 3 to pH 6. However, pH 7 will be slightly lower than pH 6 since the optimal pH for Phaseolus vulgaris is around a pH of 6.0 - 6.5. The leaves in pH 4 to 5 will be smaller and there will be dark edges or yellow leaves due to the poor absorption of nutrients (e.g. phosphorus, potassium, magnesium). How can I write an H0 and H1 for this, if my hypothesis is not linear?

a. H0: There is no significant effect of pH on plant height.
b. H1: There is a significant non-linear effect of pH on plant height.

Answer 1

The H0 for this scenario would be that there is no significant effect of pH on plant height, while the H1 would be that there is a significant non-linear effect of pH on plant height.

Step-by-step explanation:

The H0 (null hypothesis) for this scenario would be: There is no significant effect of pH on plant height. This states that the pH level does not have any impact on the height of the plant. On the other hand, the H1 (alternative hypothesis) would be: There is a significant non-linear effect of pH on plant height. This suggests that the pH level does have a significant impact on the plant height, but the relationship may not be linear.
