Hypothesis: The commercial hair product Rogooti accelerates hair growth.Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.Conclusion 2: Rogooti does not seem to have any effect on hair growth.

Explanation:

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.

A hypothesis must express what is expected to occur comprehensively. There must be a logical relation between variables. It must be objective.

To answer the question, Lisa might propose the following hypothesis, which needs to be corroborated.

Hypothesis: The commercial hair product Rogooti accelerates hair growth.

Experiment: Her family is a volunteer for the experiment, so all of them will use an ordinary hair product for a month. Before and after this period they will take notes of how long their hair is before and after the first part of the experiment. After this, they will cut down their hair to the initial length, and they will start using Ragooti for another month. After this last one, they will measure hair length again. Finally, Lisa will compare the initial length with the one after the first month and after the second month to analyze how Rogooti affects the speed of hair growth.

Result 1: When comparing lengths, Lisa will see that the hair of all her family members grew longer during the second month.

Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.

Result 2: When comparing lengths, Lisa will not see any significant difference in the hair growth of her family during the first and the second month.

Conclusion 2: Rogooti does not seem to have any effect on hair growth.
