As scientists conducting an experiment, you need to have an experimental group and a control group for testing a hypothesis. If you were a scientist, and with the knowledge you have, what kind of hypothesis would you test? Provide an example of an experiment you might conduct.

Answer #1

If would be a scientist, I would like to test the hypothesis of whether certain specific biofertilizer application increases the plant growth or not.

For this, I should take one independent and one dependent variable. Independent variable for this hypothesis experiment will be the biofertilizer and water. Dependent variables are height of plant, number of flowers, number of leaves etc.Any change in the dependent variable occurs due to change in independent variables. The control group for this hypothesis would be the specific biofertilizer, type of plant used for this testing, soil type, amount of water used etc. So this the experiment I might conduct.

As a general principle, in order to validate results in scientific experiments, scientists use controls. A control is a group that is designed to demonstrate that the results/changes observed in an experiment were because of the procedure you performed. It sets a baseline value with which the scientist can compare with experimental sample and interpret results, as was demonstrated in the previous question. In this question, we are asking you to describe the control experiments, using the same transformation protocol,...

You are conducting an experiment in which you measure two means. Your null hypothesis is that they are the same (i.e. μ1 - μ2 = 0) and your experiment will test this hypothesis with a confidence level of alpha = 0.05. You would like to be able to detect a difference in means of+/- 1 with a probability of at least 0.9. How many samples do you need to test? The standard deviations of the two groups are σ1 =...
